Cannot boot after upgrade

[thecat]

I upgraded from 3.4 loop 3 to 3.4a
First I left the bootloader unchanged, but then it wouldn't boot.
Then I re-upgraded and let the installer change the bootloader. It's located in the mbr.
It still won't boot. I can see the bootscreen of Sabayon and then itr gives me: 'cannot specify root device...'

I have a dualboot with WinXP on sda1 and sabayon with the root partition on sdb1.
I re-upgraded again and this time added to the bootloader manually:
Sabayon / dev/sda1

When I boot that from the bootscreen I get the error:
'root noverify (hd1,0)
chainloader +1

Error 13: invalid or unsupported executable format'

How can I make my fresh new upgraded Sabayon boot again?
Thanks in advance.

I think I'll just do a complete reinstall. That might be simpler than this.
My home directory is on sdb5. Can I rename my own home folder (mattijs) to something else, than install and create a new user mattijs and copy back my personal home folder to the new home-mattijs folder

Indeed that worked..

Code: Select all

Sabayon / dev/sda1

When I boot that from the bootscreen I get the error:
'root noverify (hd1,0)
chainloader +1

Well... I you have system on sda1 than start from hd0,0 not hd1,0
