|
|
Installing a new box. BIOS based motherboard, GPT partitioned sda with one single partition sda1 for root, formatted Ext4, kernel has Ext4 and GPT enabled.
I'm getting dreaded "unable to mount root on (8.1)" message.
What am I missing? _________________ My Gentoo installation notes.

Jaglover,
That looks like a missing filesystem driver, or its made as a module. _________________ Regards,

Jaglover,
What boot loader ?
You actually have two partition tables, the GPT one you are telling us about and a protective MSDOS Partition table that covers as much of the drive as it can with a single partition of type EE, which is a flag to fdisk not to mess.
Where is grub and how did you install grub?
There is no space for grubs stage1.5 so you must not move the stage2 around on disk as the stage1 loads it directly by LBA numbers.
If you reinstalled grub for any reason, you must reinstall the MBR too or the stage2 is loaded from the now free space where the old stage2 was.
Do you have more than one drive ... is grub looking at the wrong drive? _________________ Regards,

Yes I want AHCI, no clue how I left this out, although I wonder how it managed to get (8,1) error without controller support.
Bootloader is Lilo, no-multilib system. Kernel loads, just ends up panicking.
Recompiling kernel now, thanks for replies!
