PostPosted: Wed Jul 20, 2005 1:51 am    Post subject: Boot Device not found Reply with quote

I can see gentoo trying to mount the cd on sda, sda1, sdb, and sdb1, and fails. It says cannot find boot device please specify boot device or type shell for a shell. I have Windows XP on sda1, and sdb1 is one big storage partition. When I try and tell gentoo to use /dev/sda2 which is the unallocated space that I want it to use it refuses and gives me the same error. Any ideas?

looks like you trying to type in directly to grub shell??
or if its bash do you get some errors in dmesg?

The only errors are that the boot device cannot be found. This happens as the minimal live cd is booting up. It trys to mount th eboot device to sda1 (windows partition) and sbb1 (slave drive) but when it asks for me to specify a boot device to type shell for shell I dont know what to do. I try and tell it to use sba2 but it refuses. Is there something extra I have to do for sata drives? That is what I am using.

These are my errors

Determining root device...
>>The root block device is unspecified or not detected.
Please specify a device too boot, or "shell" for a shell...
boot() ::

This happens upon boot for the very first time, before I even get a chance to run fidsk or configure/install the system in anyway.

It tries to find your CDROM, but it fails. This may be because of a buggy BIOS or because the LiveCD does not have the correct driver for your CDROM device. If your BIOS recognises your CDROM then that leaves the second problem as the most likely cause of your symptoms. You may need to pass the option /dev/hda to the LiveCD to boot from. This thread shows a way of creating a new node for a USB drive. It would be similar for your CDROM.

If another LiveCD recognises your CDROM, e.g. Knoppix, then you could use that to install Gentoo (look at alternative installations in the Handbook).

Hi.

I think I've read a few weeks ago a thread about using a Plextor SATA dvd and the live-cd. You might try to search for it.
If I recall the discussion correctly, it seems that at this time it's not an easy task to use a SATA cd/dvd to boot the live-cd. If all else fails, try to use [k|g]noppix to boot and follow the Alternate Installation Handbook.

drahz,

do you mind explaining why my suggestion to read about a problem with a plextor sata dvd has nothing to do with this?

the problem occures after the reboot. the livecd is not in the drive. after reboot the root partition is what gets the block device error.

drahz,

did you read this post? If this has nothing to do with the live-cd, I must be needing some reading classes or I'm very very distracted.
