Booting newly complied kernel (hard-drive problem)

donaldtalbert · 06-19-2005, 02:01 AM

I just complied my first kernel for debian ver . 2.8.6 for intel 4 processors
and i think i might of messed up on configureing it.
after building it i get...
(this is when i boot it)
VFS: Cannot open root device "hda1" or unknown-block (0.0)
Please append a correct "root=" boot option
kernel panic: VFS:Unable root fs on unknown -block(0.0)

i think hda1 is my hard-drive but im not 100% sure. if that helps any.
if you need any more specs on my pc its few stock medion md1777 (didnt change any hardware yet). Thanks in advance.

btw other default kernels work fine.

how many hard-drives do you have?
how many partitions do you have? which one has debian on it?

post contents of /boot/grub/menu.lst (assuming grub is used) or /etc/lilo.conf (for lilo).
thanks
