no such device no such disk

sslavic · #1 6th December 2011, 06:45 AM

Hello Fedora community,

Title of the post is not from a song, it's output I get after choosing to boot a Windows Vista installation on a second hard drive. That hdd was only one in the laptop and booted well. I took it out to add new primary storage, an ssd drive, and installed Fedora 16 on ssd using a dvd. Then I took dvd reader out of the system, and put old hdd back in place of dvd. Windows did not appear as option automatically on next boot. I first booted into Fedora 16 on ssd, ran grub2-mkconfig which detected drive with Windows on it, and generated grub.conf with new entries. After restart, choosing to boot that Windows installation on second drive fails with "no such device no such disk" messages.

Attached is zip archive of my grub.cfg.

Any ideas on what could be wrong or how to resolve this one are welcome.

Thanks in advance!

Regards,
Stevo.

can you provide a picture of the failure screen? it might help figure out exactly where the problem lies.

Can you also attach /boot/grub2/device.map ?

I'm not entirely convinced about the '/dev/sdb'. As a shot in the dark, try changing /dev/sdb,msdos1 to hd1,msdos1 and /dev/sdb,msdos2 to hd1,msdos2 .

Adam,

Thanks for replying!

Attached is archive of my /boot/grub2/device.map file. Can take a picture of error during boot but basically it says:

error: no such device: %some device id%
error: no such disk

press any key ....

Have to learn about grub2 to make more sense of info in device.map, but since I don't see hd1 listed there I didn't try making changes you suggested, yet.

interesting. if you run 'grub2-mkdevicemap -m /tmp/device.map' from Fedora then look at /tmp/device.map , how does it compare to /boot/grub2/device.map ? still no second disk shown? I suspect if you use grub2-mkdevicemap to make a new device.map file with the second disk attached, then the second disk will be in the device.map , and that'll help with the problem.

New device.map is different (see attached new device.map zip archive), but still no luck with booting to Windows. Luckily booting to Fedora still works.

Here are more details that maybe could help:

sslavic: the command I created intentionally doesn't overwrite your existing device.map , it just creates a new one in /tmp for us to examine. Nothing would *use* the new one unless you moved it into /boot/grub2/ . Did you do that?

sslavic · #8 9th December 2011, 01:14 AM

Yes, of course, thanks for checking.

it would be easier if we have all the info in 1 post! can you go here and run these script, then post/attach the results..

OK, here is the RESULTS.txt

Applied all the recent Fedora 16 updates, including kernel 3.1.4, run grub2 to generate device.map and grub.cfg again, and now when I try to boot windows I get:

hd1 cannot get c/h/s values

Finding some hints that it might be some bios limitation, that it can not see the second hard drive. Machine is hp 8710p laptop, with hdd in place of dvd, and primary drive is sdd.
