after switching the boot settings from uefi to legacy, I can't enter my bios anymore.
Neither with F2 nor F12.
He shows me that "Operating System can't be found".
Did the switching for testing another OS.
Is there any trick to enter the bios to switch again to uefi mode?
Is it possible to switch from legacy bios to uefi on a dell Vostro 1000 and so how?

how to turn off the notifications that pop up in the upper right corner telling you that you have just changed from one configuration to another -- e.g. changing from tent mode to tablet mode?

What I've found are these 3 (you can see them in the picture below), now my question is: which one should I pick?
I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.
What's the difference between UEFI and Legacy and why can't I install Windows 7? I put the Windows 7 CD into the CD-Rom and the installation doesn't start up. It does start up only when I change the bios to legacy. What's the difference between UEFI and legacy? Is it possible to install it on UEFI? If not, if I will install it on legacy, will everything be ok?

I have almost applied all methods. I have checked bluetooth is enabled in the bios settings. And also I applied the method of services.msc in command prompt.
I pressed Fn + F2 during installation but bluetooth option is not going to be on. I do not think why it is giving that problem. I have uninstalled the drivers now.
I'm trying to install Ubuntu on an e6530. I changed a BIOS boot setting from Legacy to UEFI. Now the laptop doesn't even show me a BIOS screen at startup. The screen is backlit, so power is on, but shows nothing. The drive light flickers a few times, but no matter how long I wait, nothing appears.
I can't even switch it back to Legacy because I can't get into the BIOS. Hitting F12 after power on does nothing. Is there some way to get it back to Legacy mode? Or simply reset the BIOS to default settings?
I have recently been completely unable to access the set-up area of my bios on my Dell XPS 17 L702x laptop. On booting, i keep pressing the F2 key which seems to be registered by the BIOS as the text that says 'Set-Up' lights up. However, instead of entering the setup, the BIOS simply continues booting my operating system. Even if I remove all of the hard drive's, I cannot enter the set up and the BIOS boots to the PXE Setup.
I have tried reflashing the BIOS but nothing changes, the set-up is still inaccessible. I can't even change the boot order using the F12 key.
I really need access to my BIOS and I am all out of options.
I have a Inspiron 14R for about a year and half now. This computer has done this since day one for some reason:
When I put the 14R in SLEEP mode, the computer remains in sleep mode for about 2-3 hours, then the computer shuts itself off, or goes into hibernation mode on it's own. The computer has Windows 7 Premiuim.
I have the power saving modes all set too SLEEP, and none in hibernation in any of the selections. I cannot for the life of me why this computer does this. I have a Lenovo I bought about a year later using Windows 7 Premium with all the same settings in the POWER section, and while in sleep mode, it STAYS in SLEEP mode, no matter the length of time in that mode. Any setting I need to turn off, and where to find it?
I was replacing my harddisk for a bigger one. after some trail and error with the AHCI driver for Windows 7 installation, suddenly the notebook freezes before I can enter the bios or it even can boot.
Now it is stuck at the DELL logo with text of latitude e6320 series, bios revision A06. With the blue line
I already tried to remove battery and power, but no solution yet.
I changed my HP to boot with legacy CSM, but I couldn't boot from the Windows 7 boot disc. The laptop was shipped with Windows 8 configured for UEFI boot before my change. The screen after boot is blank and now I can't even get to the bios menu.
I have tried a Windows 8 USB recovery drive, but the computer doesn't seem to try to boot from flash, even with the hard drive disconnected and the CD tray open.
I watched a video of a man disassembling an HP Pavilion completely down to the base plate, but I did not see a back-up or RTC battery anywhere in the computer. If I could find the bios back-up battery for removal or reset the bios somehow with the hardware, i would do that. I waited for 4 hours without the main battery attached without any change. At this point I don't know if this model Pavilion even has backup battery. How to reset the bios to default UEFI setting without a bios menu? Note that pushing F2/F8/F9/F10/F11 and a whole bunch of other keys does not bring up the bios menu at boot time (like it did when it was in UEFI mode).
My next steps are to use the HP Recovery Media application on a 2nd computer to create 6 Window 8 DVDs and see if these will boot from the CD. If that doesn't work, I'll contact HP support and see if they can send me a custom recovery disc.
It seems strange to me that I can't even get to a bios menu in legacy mode. Is this normal? I suspect that my configuration change corrupted something and no booting will work any more. If booting from disc doesn't work, I think I'm stuck with trying to drain whatever back-up power source keeps the bios in-state, however long that is.
when I tried to play any sound (details at bottom ). Anyway, I went onto the dell website to get a driver to see if it would fix it. I had to fond this service key thing, and then it told me I needed to get these three things. They were a couple of number with a letter or two in there, meant nothing to me. So I installed one, and it came up with this grid, and the boxes were getting filled in, and then some of the, were red in the middle. My laptop was reeeaaally loud at this point. But then, the power cable went out, and I've had this problem where the laptop loses connection to battery, and it went. So then, my laptop went off. And now when I tried to switch it back on, what happens is the power button lights up, three buttons on the right light up momentarily. But the screen stays black. So then the only things indicating it's 'on' is the power button, and the three lights on the bottom of the laptop, which I have no idea of purpose. Also, my laptop is very very quiet at this point. Anyway, yeah, I've taken battery out, charger out, both out, left both out, put both in, that hasn't solved it.
I had been messing around with my playback devices (enabling/disabling) because I had tried using Skype. Originally, I had a problem where my skype calls were coming through my headphones (plugged into the headphone jack), but any other noise, coming through my laptop speakers. I sorted this by disabling my "communications headphones". And then now, I had a problem where I was in a skype call, when everything else stopped producing sound, bar the skype call. So I tried reopening my browser, but nothing, checked iTunes, and the music wasn't playing. So I thought it may have been the skype call. It wasn't, as I ended it, and still no noise was coming through. Then after a few minutes, there was a just this background noise coming through my headphones, like a fan. I noticed that it was coming out of my headphones when plugged in, but also my speakers when unplugged. Also, when I muted sound, the noise stopped, so I thought that may hint at where this problem may occur.
I just bought an Edge 130 and wanted to set it up today. But I just can't enter the BIOS! I keep pressing F1 during the Lenovo splash screen. I've pressed it repeatedly, held it down, I even tried it with the Fn button pressed. Nothing worked.
I've have been working with and professionally supporting Lenovo (and before IBM) notebooks for over 10 years and not once did I have such a problem. This is only the second E-series notebook I have ever had. I bought myself an E525 last summer and had no such problems and at work we have T-, X- and W-series.
When I bought my Inspiron 3537 it came with Ubuntu, for business reasons I needed Windows, so I removed Ubuntu and installed Windows 8.1.
Now, I'm considering switching MBR to GPT, I'm 99% sure that my pc supports UEFI and that it will work fine. In order to do that I must clean my whole hdd, that's not really problem because I have backup. What bothers me is this.
There were few extra partitions on my HDD, 350 (empty) partition with no label (it's not windows system reserved) , 3GB partition with label OS. They were put there by Dell.
Now, considering that I have to Clean my hard disk using Diskpart, and this partitions will be removed, will I lose something? Some BIOS functionality or something like that? Is it safe to just wipe them out?
From last 2 days, I have seen that my laptop 3521 Dell doesn't switch on at all. Second thing I have observed is that, when I have my charger connected to the plug point (not connected to the laptop), I see the green light on the charger as ON, but the moment I connect it to the laptop, the light from the charger turns OFF and ultimately, my laptop doesn't charge. I mean no power supplied.
The steps I have carried over so far are -
1) I have tried checking the laptop battery by taking it out and reputing it in the laptop and trying to see if it works, same problem.
2) I have tried checking if everything is okay with the charger, but still the same problem.
I have a Dell Studio XPS 13 (1340) and when i switch it on the power lights etc come on and the screen is blank. After a while it shows the Windows desktop and the laptop is ready to use but I cannot see the DELL logo at start up or am I able to get into BIOS. However when I plug the laptop to an external monitor it displays the LOGO properly and I am able to get into BIOS.
View 1 Replies View RelatedRecently I purchased a Dell Latitude D830 motherboard as a replacement for the damaged one in my own system.
The seller didn't tell me that the system has a customized bios and a password, instead he announced it as 'password free'. The board is working and I can enter the BIOS but all settings are locked with a password.
As the seller refuses to take it back, I need to reset the system. The first owner of the board is known and I have the service tag ready. Is there any chance to reflash an original DELL BIOS and to reset the password(s)?

View 1 Replies View RelatedMy machine is Lenovo Z580 with Windows 7. Some time ago I accidentally installed Linux Mint on my whole HDD, so all the partitions and files (including recovery partition) were erased. I then installed back Windows 7 and partitioned the HDD.
However, since the incident, I'm unable to enter BIOS. I'd like to change boot sequence, because the laptop wants to boot from network, displays an error, and then boots from HDD and Windows 7 starts. I can access boot manager with F12 during boot, and the entries are (those aren't the exact names of course, except the first one):
1. ubuntu <- yes, that's how it's called. I guess it's a remnant of Linux Mint installation
2. booting from network
3. booting from HDD
4. booting from DVD
5. booting from USB
I tried the following things:
1. pressing F2 at boot. it used to work before the incident, now the laptop ignores it and proceeds to attempting boot from network, displays an error, and then boots from HDD.
2. using Novo button instead of power button, then choosing "BIOS setup" option - the laptop still proceeds to boot OR displays black screen and need to be shut down
3. removing boot entries using Ubuntu via USB stick [URL] ..... - I can't remove any entry, because after using
>efibootmgr -v
no list appears, and when I enter
>efibootmgr -B -b 001
or any other number, I get an error that the entry wasn't found.
I can't flash BIOS because Lenovo didn't provide the necessary file for this model. I also can't sent the laptop to repair because my warranty period ended two months ago.
So, I flashed the file attached here: [URL] .... and everything works now! the "ubuntu" entry has been automatically deleted and I was able to access BIOS and change the boot order.
Before installing ... write down MAC address of your LAN card, because it'll get deleted after BIOS update!
1. press windows key+R, type cmd and press Enter.....
2. in the opened command window, type ipconfig /all and press Enter, find the entry regarding your Ethernet connection and write down the physical address....
3. Flash BIOS update
4. After reboot follow this guide: [URL] .....
