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).

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...

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 P/Y/Z Series :: Partitioning Hard Disk In Z510

Apr 24, 2014

I purchased Z510 recently with 1 TB hard disk. The problem is that it came with only 2 partitions :
a) Windows (C) - 891 GB
b) Drivers (D) - 25 GB
When asked with the support, I was told that if I make new partitions my warranty will void. and if anything bad happens on the software part I have to pay for that to fix it.
It is very difficult to work on a system with only above partitions.

Lenovo ThinkPad W Series :: W540 - Boot From Second Hard Drive?

Jan 29, 2014

I've recently got an ultrabay adapter and wanted to know if I could run two separate OSs, one from each hard disc.
Effectively, I would like to have one version of windows on the internal HDD for general day to day stuff and one as a programming environment and be able to select which to boot from at start up.
I know I could just use a VM, but some of this stuff (Siemens PCS7) can put quite a strain on the system and I'd rather not have that overhead.

Lenovo P/Y/Z Series :: Z510 Random Shut Downs (hard) When Plugged In

Jun 8, 2014

My Z510 has been randomly shutting down when plugged in, but doesn't have this issue when running on battery. I contacted Lenovo and they sent my a new power supply but the issue continues. I called again and they instructed me to repair-install the Lenovo power manager and do a disk check. The issue still continues.

It used to happen when running something intensive like photoshop or a game and only if charging over 75%, but now it'll happen randomly. I can be sitting staring at the laptop with no programs running and it'll shut down.

Lenovo Y410 P/Y/Z Series :: Unable To Boot From The Windows 8 Installation Disc Or From The Hard Drive

Nov 6, 2014

I have a Lenovo Y410P that will not boot. The BIOS only sees to PXE boot. It does not attempt to boot from the Windows 8 installation disc, or from the hard drive that I reinstalled Windows on myself. I can boot to both of these on other computers, so I know they are not the problem. I'm thinking it's BIOS or motherboard related, but I'm not sure where to go from here.

Dell Studio 1737 :: Hard Drive Recognition After BIOS Update

Feb 17, 2013

I was trying to update my old studio 1737, and updated the BIOS to A09 while doing an otherwise thorough and effective diagnostic (from Dell website). Now when the BIOS does identify my hard drive its inaccurate (intermittent ID of the HDD, showing no HDD sometime and a Samsung other times). So, laptop fails to boot, saying operating system not found. Am trying to flash BIOS using last working version on USB stick, following advice found on internet. Well out of warranty period.

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 T400 / T500 :: T440P - USB Boot UBCD4WIN Cannot See Hard Drive

Nov 25, 2014

IBM/Lenovo laptops and desktops for a long time. I recently purchased a T440P laptop with a standard 7200 RPM HDD in it. In the past, with previus models, when I wanted to troubleshoot the current Windows install (virus infections etc) I would use UBCD4WIN on a USB stick to boot the computer to USB and access the hard drive to pull data off or remove files infections etc. With this new T440P I cannot seem to see the hard drive when I boot it up with the USB stick.

I can boot the computer just fine and run the USB based OS without trouble but I simply cannot see the hard drive.

So far I have tried:
-Adjusting UEFI to Legacy and/or "Both"
-Adjusted CSM to Yes and No
-Disabled/Enabled Secure Boot

and several combinations of all of the above in hopes it was the issue but it doesn't seem to change my ability to see the hard drive. It simply doesn't show up.

The drive itself (in the T440P) is a standard HDD (not SSD) and is formatted NTFS with Windows 7 64bit installed on it.. The UBCD4WIN is a basic "Windows XP" x86 (32 bit) OS on a USB stick and the USB stick is formatted FAT32.
In previous lenovo models (T400/T410 etc) all I had to do was switch AHCI to Compatibility and I could see the drive but this one is giving me a real fit and I am not exactly sure if its a controller driver, UEFI or something else.
how to see the hard drive when booting to the USB UBCD4WIN stick?

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

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...
