Acer :: (6935G) Boot Problem After Restart (cant Access Bios / Boot From Disk Etc)

Jan 9, 2010

I got this laptop a few days ago, I currently have 7 and XP installed on it and kind of have vista...(read further down).

My 7 seemed to break today after playing around with a program called powerstrip trying to get my external monitor to show the right resolution (I've realised now the cable vga was broke, but meh) but this is not the full problem, after windows 7 failed to boot I tried to boot xp after turning it off during the windows 7 splash screen and now im stuck with a dash when I turn the laptop on (I dont know if its actully related to something I've done or not).

If I turn the laptop on a flashing dash comes on in the top right, it then stops flashing and turns into a none flashing dash further up the screen and just locks here and I cant do anything at all other than trying to restart it. When I had this problem previously (at least I think this problem) on my desktop it usualy turned out to be something usb related but I have everything unplugged (all though the bluetooth adapter light is on when it is doing this) so I realy dont know what to do...............

Acer :: Aspire Timeline 5810tz Won't Boot, Can't Access Setup Or Bios

May 7, 2010

I just got an acer aspire timeline 5810tz, which came with vista, so i was in the process of reformatting it to have XP, which i've done several times on my previous laptops. When i changed the bios to IDE, which is what i read was the correct setting (perhaps this is where my problem is?), i found that i could no longer boot the computer or access setup, bios or the boot menu. When i attempt to do any of these things, the computer just sits on the logo screen.

i'm getting fairly desperate at this point, having tried a large variety of solutions, key combos, removing the battery, etc.

Acer Aspire M :: Boot Configuration File Being Invalid - Cannot Access BIOS

Dec 26, 2014

My Aspire M laptop will not boot due to the 'boot configuration file being invalid', at least, this is what the 'Recovery' blue screen states.  The blue screen offers to 'Press Esc for UEFI Firmware settings, but is not responsive.  I've tried F2, F8, F10, Alt+F10, F12, Space Bar, Delete and Break to try to activate the BIOS interface, all equally unsuccessful.
I followed the instructions to purchase recovery tools from Acer, but without being able to access the BIOS to set the boot order, I've just sunk another $25 into a laptop that doesn't work. The cost of service exceeds the cost of the laptop, so I'm inclined to continue trying to repair it myself.  If it cant' be repaired, there is little chance I'll purchase a new Acer to replace it as this has been a very frustrating experience.

Acer :: Creating BIOS Flashing Boot Disk

Dec 4, 2009

Reason for this is to flash your BIOS the safer way.

Windows has alot of services that can potentially hang the flashing process, hence DOS Mode where no other process is running is the safe way to flash.

First of all get the package here

Extract all the files to Desktop

Go into the folder.

You should see a HP Drive Key Utility.

Install it.

Open the Program With Administrative Permission with Right Click as shown below:.......

Lenovo T400 / T500 :: Won't Boot (can't Access BIOS)

Nov 9, 2009

I have a T400 2765-P3U model, and it won't boot up.  When you turn it on, you see the Thinkvantage logo and it stays there.  Trying to access the BIOS is non-responsive.  I connected the hard drive to see if it was a hard drive issue, but it's not.  The hard drive is response when connected via USB.  I can't get past the Thinkvantage logo, no response when attempting to access the BIOS.  It's still under warranty, so I'll probably send it in for repair but thought I'd give it a try fixing it before hand.

Dell Inspiron 17R :: Cannot Access BIOS Or Boot Order During POST

Jan 3, 2013

What I Was Doing:

All I wanted to do was install an SSD (SanDisk Extreme 240GB) as my primary drive using factory recovery created from Dell Backup and Recovery/Recovery Media from USB drive.... I was trying to update firmware on the SSD. It requires a download and the creation of a thumb drive to which one boots after adding it in the BIOS. Ever since I tried using that thumb drive during boot (on power up it was in a USB slot with the intention of opening BIOS and setting that thumb drive as a boot device to complete firmware update) things have been a mess.

The Problems:

I have run into a situation where no matter what key I press during startup, it has no impact on the startup. Main problem is that F2 will not open BIOS. F12 does not show Boot Order.

 Here are the symptoms:

Cannot access BIOS or Boot Order during POST All partitions on the factory 1TB hard drive now show in Windows File Explorer whereas previously only the partition labeled C: OS was shown

Potentially Stupid Things I Tried:

I discovered that if there are no hard drives installed, the system will boot to a DOS-type screen with options for Boot Order (with no drives it lists only Network Boot), Setup, Diagnostics, and Boot Configuration.

Setup takes me to the BIOS (vA11) but obviously with no drives showing Diagnostics takes to me to a test suite which when run gives me an error on the video memory but all else tests OK (tests of the video memory from within the Dell Suite within Win 8 show no errors) Boot Configuration gives me Legacy, UEFI Secure and UEFI Not Secure

I also downgraded the BIOS from A11 to A08 and then back to A11 in hopes of getting back access to BIOS but no luck.

Lenovo ThinkPad L R/SL :: R400 Freeze On Boot Before BIOS Access

Feb 10, 2013

My R400 laptop (7447-W14) suddenly freezes on boot: it displays the early logo ("thinkpad, to interrupt normal startup, press the blue Thinkvantage button"), and waits forever, neither the bios menu nor the operating system (windows and ubuntu in dual boot) appears.
I can shutdown by holding the power button more than 5s, but on reboot, the same freeze come back, whatever I do:
- holding the F1 key before and after powering on
- holding the "ThinkVantage" button
- doing this on battery, or with power supply (with or without battery)
- trying to boot on an external USB HD drive
It does not seem to be a CPU problem (nothing would be displayed), nor RAM or harddisk one (it is cheked later, at BIOS time).
In fact, I was wondering wether removing and putting back the small battery of the mainboard would solve this problem ... but this battery seems not to be eaysyly found. At least, it is not under the keyboard, where the RAM is.
of course, warranty has ended ... any way, before I throw this laptop to trash ?

Lenovo P/Y/Z Series :: Z510 - Default Boot Device Missing Or Boot Failed After BIOS Update

Dec 13, 2013

I get the error in the Title after i tried to flash the latest BIOS update for the Z510. I can press ok and then get into the boot manager but i cant choose anything there. Also I cant boot from a Disk with e.g. XP on it.
I also tried the Inside BIOS crisis mode (fn+r) with the BIOS file on my USB drive but it doesn't work and tries to access the file on the USB drive but boots normally instead to the error again. (Couldn't try it with removed battery as I have to remove the whole back to remove the battery on the Z510).

Apple :: Aluminum Macbook - Odd Restart - Indicating A Boot-up

Feb 17, 2009

I'm experiencing an odd restart issue with my Aluminum Macbook (see sig for specs). It is an occasional issue, happening maybe once every week or two.

Basically, it goes like this. I restart my machine for whatever reason, and as it reboots I get the apple (indicating a boot-up). Instead of booting up in 30 seconds as usual, the apple just sits on the screen for a while and then finally turns to an X. This continues each time I reboot. The only fix, I have found is to disconnect the power and remove the battery for thirty seconds. Then everything reboots as normal.

This has happened to me several times, the same scenario.

Does anyone have a hint for me on what might be happening?

Lenovo P/Y/Z Series :: Y510p Freezes While Playing A Game - Boot Fails On Restart

Feb 4, 2014

I've had my Y510p (8GB RAM, DVD Ultrabay option) for a bit more than four months now and it's been working perfectly for most of the time- however, two days ago, while playing a game the computer or the game itself froze. After trying to bring the Task Manager up/kill the game, I decided to restart it- I turned it off, but once it came back on, it had decided to start "Preparing Automatic Repair". After several times unsuccessfully "repairing" (after which again "preparing") it (it had given me an error, something with Srttrail.txt file), I decided to look up and search the Internet for people with a similar/the same problem- none of the methods worked. So, I decided it could've been from software I've installed or similar- I didn't have things THAT important (I haven't made any back-ups, nor a recovery USB), so I made an initial state lenovo recovery  using the Novo button.

After several more fixing methods (unsuccessfull again, people suggested getting into the command promt, using the chkdsk command, but it was in a drive called x:, couldn't find other drives/changing from UEFI to Legacy Support in BIOS settings, I changed them, then changed them back to defaults) it started giving me the "IPv4/IPv6 Network 0 (MAC Adress) boot failed" errors and several tries more, now it constantly gives me the "Windows boot Manager boot failed" error, followed by the IPv4/IPv6 ones. after which it takes me to a blank bright-blue screen with my only cursor visible (similar to what it does i I tell it to go to Lenovo recovery menu now). Also, after trying to turn it on (in the current/last state) it gave me the 0xc000000f error. So, what's happening (the HDD is recognized in the BIOS, the laptop itslef hasn't been moved more then four or five time and used properly)? I have no instalation/repair disc with the laptop.

Acer Aspire E1 522-3657 :: Default Boot Device Missing Or Boot Failed

Oct 11, 2014

I have a Acer E1 522-3657 computer, which my son set-up for me but did not make the recovery disc(s). The unit is just outside of the warranty period when the hard drive failed. The hard drive just makes a clicking noise and after the logo screen appears it goes to a blue screen with a box that has the following message with in, "Default Boot Device Missing or Boot Failed. Insert recovery Media and Hit any key.....Then Select 'Boot Manager' to choose a new Boot Device or to Boot Recovery Media.
I have installed a brand-new Western Digital 1T Sata3 harddrive to replace the Toshia 750 GB original Drive. After turning the computer on and at the logo screen I press and hold F2, this takes me to the InsydeH20 Setup Utility Screen. I see under the "Information" menu that the installed harddrive model and serial number appear. I see in the "Boot" menu, Boot Mode: "UEFI" and Secure Boot: "Enabled".
Under the "Exit" menu, Exit Saving Changes is highlighted. When I press F10 a "setup Configuration" box appears asking to save configuration changes and exit now? "Yes" is highlighted to which I hit Enter and are returned to the "Default Boot I then hit ecs twice and are at a black screen with the message No bootable device -- Please Restart system_appearing in the upper left corner of the screen. I then push and hold the power button until the computer shuts off.
I have ordered from acer the "Acer E-recovery Media Disc Set", which is specific to the SNID of my computer. I have not attempted to format the new hard drive in any way.  I assume the E-recovery Media Disc Set will handle that operation due to the multiple partitions required.
In view of the above situation, do I need to set up the computer in any way before I start to utilize the E-recovery Media Disc set. I assume the Media will be on CD's. The computer was running Win 8.0 which was updated to Win 8.1 and was running very well, very stable.

Acer Aspire R7-571 :: Locks 3 Min After Boot With BIOS 2.09

Oct 28, 2014

I recently updated my bios on my R7-571 and it has caused me great woe.  My computer will lock hard between 3 min and 3:30 min after bootup if I don't disable the WIndows Managment INstrumentation service.  THis of course caused other problems on services that depend on that like LogMeIn.  I need a solution to this.  Either a way to downgrade to an earlier bios which I don't think is possible without a version of the bios updater that will support this, or a newer bios that addresses this issue.

Acer :: 5730 Boot Bios Password And Wanted To Disable It

Aug 9, 2009

Now I am not after any passwords or any thing but I think this is disgusting.

My wife has an on boot bios password and wanted to disable it. She asked me to do it because I work in IT so it shouldnt be a problem.

I logged in with her password. Went security, user password, Press enter, typed in existing one then new password blank and confirmed it with another blank password. Rebooted and now it prompts for a password and we are stuffed.

Is this me being stupid did I do some thing wrong is that not the way to do it ?
Its appauling. We had a customer in work whos laptop was sent away to be sorted because he had the same problem. At the time I thought he was bit silly but now I can see how it could happen

Acer :: Accessing BIOS Of 5920G To Change Boot Order

Sep 27, 2008

I recently purchased an Acer Aspire 5920G and am delighted with my purchase.

The laptop is presently working well (touch wood !) but in case of future computer catastrophe I used the eRecovery facility to create a full back up and also create recovery DVDs.

Being a "belt and braces" person I have also bought, downloaded and installed a copy of Acronis True Image Home 11 which I saw recommended in a computer magazine.

As part of the Acronis process, I created a rescue dvd using its standard tool.

I am now required to check that this rescue DVD boots correctly.

This involves entering the 5920G's BIOS and temporarily amending the boot order.

I understand I can do this by tapping the F2 key repeatedly before Windows starts. Is this correct?

Is there any kind of password required to enter and/or amend the BIOS ?

Are there any risks in this process, what are they and how can they be avoided/minimised ?

Acer Aspire V3-371 :: Cannot Boot To MS Windows After Upgrading BIOS Form V1.05 To V1.08

I try to reinstall MS Windows, but I see a notice "Windows can't be installed on this drive" with details "Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks".

Dell :: M1530 Boot Disk?

Aug 4, 2009

I am trying to create a bootable CD or bootable USB flash drive from which to run a Dell bios update.

It seems I keep getting close but then something fails.
For example, I followed these instructions but after a few seconds the Windows 98 splash screen stops moving and nothing happens.
I've tried FreeDos on a usb flash drive, but I get "Bad or missing command interpreter". I tried one suggestion from the FreeDos site but nothing changed.

I need the boot disk to downgrade from bios A12 to A09 to hopefully solve my battery charging problems. This is a known fix.

EDIT: The battery level is too low, and the bios update won't work unless the battery is at least 10% charged. Running the bios update from a boot disk with the /forceit command line argument is supposed to get around this

Dell XPS L702X :: UEFI Mode Enabled But Can't Access Firmware Setup And Boot Menu

Oct 28, 2012

Yesterday I flashed the firmware of my XPS L702X to version A19, which enabled UEFI boot mode. I decided to go ahead and try to install Windows 7 in UEFI mode on a GPT disk. Installation succeeded, booting failed however. Then I read a message on the web from someone who succesfully installed Windows 8 on the same machine in UEFI boot mode on a GPT disk. So I decided to try Windows 8 instead. Installation failed. Using the recovery menu from the Windows 8 installation media, I wanted to try and see how far installation had come and more or less accidentally selected in some "Advanced options" menu to reboot to my USB flash drive (where the Windows 8 files were on). Rebooted fine. Then I shutdown, using the regular option.

When I turned on my machine again, I found out that pressing either F2 or F12, for the firmware setup and the boot menu, respectively, didn't work anymore. The firmware recognised my input, as the text in the lower right of the Dell splash screen became lighter, but instead of entering setup or the boot menu went straight ahead to boot my existing and working Windows 7 installation on my first (MBR) hard drive instead.

So, in short, I am locked out of setup and the boot menu. I have already tried reflashing the firmware, but without any luck. What to do now?

Acer :: Boot Issue On Aspire 2930 Laptop Corrupted BIOS

May 9, 2010

The strangest thing has happened to my Acer Aspire 2930 laptop today.

I shut it down last night as I normally do, then this morning I turned it on and it wouldn't boot. It goes through BIOS and startup, but then it stops. It doesn't start loading Windows XP from the hard drive, it doesn't recognise boot CDs/DVDs. When I go into the BIOS, everything looks normal except the boot portion. There are several options there, but they don't say what they normally say. For instance, the first boot device, the hard drive, is completely invisible. What I mean is that the option is just not there, but when you move the selection around with the keyboard, you can tell it's supposed to be there. Look below for a better explanation. The other options are there, but they aren't recognising the devices. I have a friend with the exact same laptop and her BIOS shows everything as it should be. She's here now and I'm typing this on her laptop because I now have two dead computers here at home.

I don't get it. It's almost like the BIOS somehow became corrupted. I didn' t even know this could happen without attempting to flash the BIOS or something, and that's not what happened. I have never flashed the BIOS on this laptop. Not only can I not figure out what happened, there doesn't seem any way to fix it. I mean, if the laptop doesn't recognise any devices to boot from... I was thinking about taking it apart and resetting the CMOS, taking out the battery. I think that's the best I can hope for at this point.

I don't have any way of cloning the BIOS from my friend's computer so I guess the next step would be to get a new BIOS chip if the CMOS reset doesn't work? The laptop is unfortunately one month over the one year warranty. I read that there's a way to get the laptop to read an external USB floppy diskette drive regardless of the status of the BIOS, you are supposed to hold the function key plus the escape key or something when you turn on the laptop a couple of times, and then it magically reads from the floppy drive. I would have to somehow buy or get a drive, but I haven't even seen such things in years. Things I can try?

Here is what my BIOS looks like compared to my friend's:


2. IDE1 :
3. USB FDD :
4. Network Boot :
5. USB HDD :

My friend's:
1. IDE0 : Hitachi HTS542525K9SA00
3. USB FDD :
4. Network Boot : Realtek Boot Agent
5. USB HDD :

As you can see, there is definitely something wrong with my BIOS and I believe that's what is causing the computer not to boot.
