Lenovo P/Y/Z Series :: Z50-75 Won't Boot After BIOS Update

Sep 28, 2014

I just bought Z50-75 with AMD FX7500, 8GB Ram and FreeDOS. I installed Windows 8.1 Pro, and they pulled some drivers during the installation, and I went to Lenovo sight and downloaded all the rest (graphics, camera, etc.), after each installation the computer restarted normally and all was O.K. The last drivers that I saw on the site were BIOS drivers, and I downloaded those to and it started the installation after which it said:"The system will now restart for changes to make effect", and it did, but, it would not boot up after that, all it did was show me this on the screen:
And I tried both of the options (the second one with the Windows CD inside), but it just stays where it is, no effect.

I can enter the bios and change the settings, but none of them seem to work because this is the maximum where it will go, the only difference is when I change from AHCI to Compatible mode, it restarts and than I have a blank screen, I have to use the One button Recovery to get back to this one from the picture above...

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).

I bought windows 8 .1 machine from factory. Then I had local shop install 8.1 on larger ssd. I just performed latest bios update and now machine will not boot.

Lenovo X / Helix Tablet :: Won't Boot After BIOS Update

Apr 26, 2013

I just did a BIOS update the other day. No idea what version it is. When I booted it said it "detection error on HDD...". I have since reset the BIOS options to default, and now it boots to a DOS-like boot screen that shows the ATA HDD0 drive. But selecting it and hitting enter just flashes the screen and nothing happens.
When I attach a USB thumb drive with Linux, it shows up in the options on the DOS-like boot screen, but selecting it won't boot from it.The laptop is now totally uselss and I'm losing days of time and it's a major problem.

Lenovo Yoga Pro 2 Flex :: BIOS Update Now System Won't Boot

Dec 4, 2014

I wanted to do a fresh install but my restore files are in Windows 8 and I wanted 8.1. I used my 8.1 pro disk and created a bootable media for installing using USB. I had to go into the BIOS and change it to legacy before it would see the USB drive. Went ahead and deleted all the partitions then created a single new one for windows. The installation worked flawlessly then I went ahead with the driver installs.

The very first driver was the firmware update. The system updated the firmware without any issues but once it rebooted I only receive the following message "Default Boot Device Missing or Boot Failed. Insert recovery Media or hit any key. The select 'boot manager" to chose a new boot device or to boot to recovery media. When I go hit any key it leaves me with no boot options probably due to them being legacy options. I've tried F2 on startup to get into the bios and change it back to legacy but this never works.. I have also tried F12 trying to get it to let me select the startup drive.

Lenovo Yoga Flex 2 :: 15D - Boot Fail After Latest BIOS Update

Dec 11, 2014

I have a severe problem (I guess) after the latest BIOS Update. Windows 7 freezes during startup.

I own a 64-bit Lenovo FLex 2 15D with AMD A6-6310 and R4, 4GB RAM and a SSHD (8GBSSH). I purchased it without OS and installed Windows 7 - which worked fine so far.

I yesterday updated the BIOS with version 9FCN23WW (for Win7 and Win8), the latest BIOS update. A mistake, it seems.

After Reboot, I first had to disable Secure Boot in the BIOS, because it would not let me boot at all. I figured out how to get into the BIOS-Setup to disable this (press Enter 2x, press Tab when in the Boot Menu to access the "Apps Menu", then "SETUP").

Now Win7 begins to start up, but freezes during the startup process (the splash screen with the win flag freezes and looks a bit strange. I used the "protected mode" Windows Startup and saw that the process always hangs when loading "amdkmpfd.sys".

That is basically it.I guess I have to find a way to re-install the previous version of the BIOS.

Now about what I did to fix this (poor, but I tried):

If I try to start from a Win7 installation CD-ROM (actually it is one for Dell PCs, but I guess that is not the problem) and press a key to boot from CD, Windows loads files, shows "Starting Windows"  and at a certain point again just freezes. When I -do not- press a key, WIndows Boot Manager shows up and mentions that "Windows failed to start (etc.)" "File: EFIMicrosoftBootBCD" "An Error occurred while attempting to read the boot configuration data."

I can't even boot into Linux on a USB stick, because the Windows "Error Recovery" won't let me when I try (just offers to boot to Win7 in protected mode - it could be that it fails immediately and jumps back to Win Startup).

Lenovo T530 T400 / T500 :: Boot Failure After Thinkpad BIOS Update

Mar 26, 2014

After the latest system update from Lenovo System update, my laptop T530 doesn't do a successful cold boot. A warm successive boot (with interruptible boot screen) works fine.
But cold boot always fails and the system powers down in less than 5s. This is seen after the BIOS updated to restore to older version of BIOS(downgrade it)?

Lenovo B / G Series :: G40-70 Bricked By BIOS Update

Jan 6, 2015

My Lenovo G40-70 that I've just bought 6 months ago where I accidently bricked the laptop after BIOS update. It seems during the BIOS updating process it when well but after 2nd reboot there's some message on the screen that the BIOS failed to update factory setting and it freeze on the message for quiet sometimes. After a long wait I decided to long press Start button for hard reboot. Then the scary part comes in where it seems the laptop can't longer shows the Lenovo logo & cannot even boot to Windows, just black screen.
I would like to tried myself first before ending up with warranty claim since I'm worried I've brick the warranty due to wrong BIOS update procedure....

Lenovo B / G Series :: B575 BIOS Update / Flash Utility

Feb 13, 2012

I'm looking for a Lenovo B575 bios update/flash utility since my BIOS has gone bad. I cannot change/save changes and cannot restore to defaults.
I cannot find bios updtae on lenovo site (not on drivers for B575 and not under the drivers matrix). I've even tried via "Phoenix" as it's their Bios, no good. And even via a third side component (biosagent plus) that should have Phoenix bios, still no good.

Lenovo B / G Series :: G580 BIOS Update Sets Password?

Jun 10, 2013

I have recently downloaded a BIOS update for the G580 - version 20150, and ever since that I am locked out of the BIOS setup menu. It asks for a password, however I haven't set up one, and such, I am unable to change any of the settings.
Changing the values there would be important, because the settings seem to be reset to a default state, for example, I am unable to start any 64bit virtual machines because hardware virtualization is disabled. I was running Qubes OS too, but I am also unable to boot off legacy (MBR partitioned) devices, which I do occasionally to test some new Linux distro when it comes out.

Apropos Linux: as soon as the system starts booting, the screen goes completely blank, and I have to keep pressing brightness-up to see if the system had started. Brightness controls also seem to behave strange under MS Windows too: on the lowest level instead of dimming (what it did before), the screen goes completely blank. The only good thing in this update is that bluetooth now seems to work more reliable under Linux.
Is there a way to remove the password lock from the BIOS and/or revert to the previous version to avoid the screen blanking issue? Would reverting the update also remove the password? If the password can't be removed, is there a safe way to change the settings from a running OS?

Lenovo ThinkPad W Series :: W530 - 32 GB Of Memory Showing Only 16 GB After BIOS Update

Aug 23, 2014

I recently upgraded my ThinkPad W530 laptop BIOS from version 1.11 (which it shipped with) to the latest, version 2.59.
After doing so, my two 16 GB DIMMS are not only showing up as 8 GB each, thereby cutting my usable memory in half from 32 GB to 16 GB.
I ran through all the normal hardware checks to ensure that one of the DIMMS wasn't bad.  I tried each DIMM separately, tried in different slots, etc.  They both show up just fine and even pass the memory quick test in the BIOS.  Only, they are showing up as 8 GB DIMMs.
Is there a feature in the latest BIOS that would somehow limit this?  It was working fine at 32 GB before.
And, unfortunately, there is no reverting back to BIOS v.1.11 from anything after v.2.55.  It asked me if I was sure I wanted to proceed...this was the last type of problem I expected to see though.  (I also tried reverting back to previous versions of the BIOS that were allowed and it didn't work...

Lenovo ThinkPad W Series :: W540 UltraNav Trackpad - Stops Working After Newest BIOS Update

Dec 5, 2014

Both me and a friend of mine have Lenovo W540s.  Everything was working perfectly fine with all of our hardware, until today.  A BIOS update came out and installed correctly on both of our machines.  After this update both of our UltraNAV features on the trackpad are all dead.  After that first restart a message appeared "finding new hardware" and it found a generic mouse on the laptop.  Now when I try to re-install the UltraNav drivers, it says no hardware found.  I tried both the drivers on Lenovo.com and the manufacture's website all with no luck.
How to fix our UltraNav pads?

Lenovo ThinkPad W Series :: How To Change Boot Order In BIOS

Jun 8, 2010

I am trying to use the Lenovo Diagnostics Bootable USB. I have to get my BIOS to boot from the USB before my SSD.
In the BIOS, the Startup > Boot menu already  looks like the USB is listed first. But when I do a hard boot, Windows still boots from my SSD.
Here is the startup order listed in the BIOS:
3: USB CD:
6: ATA HDD1:
See, the USB is listed first.
Why doesn't my system boot to the USB? What do those symbols in the boot order mean? For example, why are there three USBs?

Lenovo P/Y/Z Series :: Y580 - New Crucial M4 MSATA SSD Not Showing In BIOS Boot Order

Jun 22, 2013

I cannot select my new SSD (M4 mSATA) in the boot order in the BIOS.
The mSATA drive DOES show up on the BIOS info page (first BIOS screen) but does NOT appear on the boot order page. The drive is visible and formatted in Windows 8 64bit and I can copy files to it,
Computer: Lenovo IdeaPad Y580 with a 1TB HDD (i7 CPU, 660M COU, 8GB RAM, etc.)OS: Windows 8 64bitSSD: Crucial M4 mSATA 256GB Model # M4-CT256M4SSD3Windows shows the drive as operating correctly. After some fiddling I did use disk management to populate the volume (238GB available) and assigned a drive letter. I successfully copied a txt file and can open the file.

I have created a recovery DVD but it doesn't recognize the drive when attempting to use--although I can see/use in Windows.

I have also removed the HDD and rebooted a number of times. So the drive is working but I cannot set it as a bootable drive. The things I have tried:

>>>Have you tried the ssd as the only drive>>> Yes.
>>> are both drives on the same sata contoller have you tried the ssd in the hdd port?>>> he SSD is mSATA and has a different port than the HDD (which plugs into the SATA port). I have tried w/o the HDD plugged in,

>>>could it be that the hdd has ahci and the ssd doesnt or vice versa>>> I have not tried disabling AHCI yet as a quick browsing showed this bricking some systems.

>>> See the Bootmenu of the BIOS setup utility. Make sure that the Boot Device Priority in the BIOS setup utility is set so that the computer starts from the device you want. >>> Doesn't list it as an option on the priority screen, BUT it is listed on the BIOS information page as recognized (HD0 I believe).

>>> Press F12 when the Lenovo logo appears on the screen while the  computer is starting up to select the device you want the computer starts from.>>> Does not list the SSD drive as a boot option. Tried w/ and w/o the HDD installed.

Lenovo X Series ThinkPad :: X230 Kingston RAM - Just Flash And BIOS Doesn't Boot After Pressing Power Button

Unfortunately after installing new memory sticks (combinations don't matter) my laptop doesn't power on. After pressing the button there's just a flash and BIOS doesn't boot.
Everything is back to normal after restoring the previous RAM configuration.
Is there something wrong with my memory sticks or is it some kind of bior issue or maybe something else?
