I have a new desktop computer: a LENOVO model 3493-BFG with Windows 8.
I started the computer without any problem. Once Windows was automatically set up, I created a recovery media (an USB hard-drive).
I then restarted the computer to see if the recovery media can boot. I was unable to use it because the BIOS displayed Error 1962: No operating system found. Press any key to repeat boot sequence.
I the rebooted without any USB device connected but the same message appear.
If I press F12 during the BIOS POST, I then have the list of bootable devices. I select the hard-drive and the system correctly boot.
So I configured BIOS to keep only the hard-drive. But the same error stops the boot process. I then reboot, press F12 then ENTER, and it's okay.
Whatever the way I boot (cold, or a reboot from Windows), I get the same message Error 1962: No operating system found. Press any key to repeat boot sequence.
I reseted the settings to BIOS defaults (inside the BIOS). Nothing better.
I used the clear CMOS switch and saw the settings where reverted to defaults. Nothing better.
I flashed the BIOS to latest version, which is only one week old. Same error.
I configured the BIOS to disable UEFI, I tested I don't remember what. Always the same error.
I used another hard-disk, with Linux. Set the BIOS to accept non UEFI boot, and everything was ok.
I put back the correct hard-drive and BIOS settings. No boot if I don't use F12.
I disconnected the DVD drive... tadammm... the system booted.
I changed the SATA port of the DVD. Same boot error.
I changed the DVD drive. Same boot error.
I inverted DVD and HD SATA ports. Same boot error.
edit: disconnecting the DVD drive no longer allow the system to boot without F12.
In short, I can boot:
Using F12
or without the DVD drive (edit: this even no longer works)
Anyone have an idea to solve this problem ?
Have you reordered the boot device priority and save the settings to BIOS? – Brad Patton – 2013-03-01T19:58:29.287
same came to mind, what is the boot-device priority? – Gjordis – 2013-03-01T20:08:22.100
1The boot device priority is written in the question: "So I configured BIOS to keep only the hard-drive". BIOS default don't works better (USB devices, then DVD, then HDD). – Bertrand SCHITS – 2013-03-01T20:25:00.850
Good question but this is sounding like a firmware issue, or maybe when you booted the USB stick it modified the Windows bootloader on your hard drive somehow?? – allquixotic – 2013-03-01T22:07:20.860
