On a failed boot, can you reach the rescue system from the initramfs?=
(The message is something like "enter password for rescue or ctrl+d) I= f
so, are you able mount your actual root partiton (sda5) manually?


No, unf= ortunately. But I am able to use the grub console prior to boot.

By doing so, I have listed the command about = to be used to boot the first entry in the grub menu, it installs some modul= es. In regard of file systems, it only loads a ext2 module, and the root pa= rtition is ext4 formated.

Although this kernel has ext2, ext3 an= d ext4 built in (not modules), can this be a cue?=C2=A0 Right now I am prep= aring to format the root partition as ext2, just to check this out.

Thanks again

It didn= 't work, so I suppose the embedded ext2, ext3 and ext4 in the kernel is= not the issue, and might be working.=C2=A0 Going to explore the grub conso= le now.

Thanks
= Francisco


In = the grub console, prior to boot, I was able to mount any partition using co= mmands like:

root=3D(hd0,msdos5)
and then listing the directory tree structure with " ls / " gave = the expected results.

Francisco

I think I might= have found it.=C2=A0 Although I have selected in the kernel "menuconf= ig" to compress the initramfs using gzip and deselected all other deco= mpression forms. a simple "file initramfs-xxx" told me that it wa= s "XZ compressed data", so now I am rebuilding the kernel with al= l decompression algorithms built in.

I will (hope) soon post the results.<= br>
Thanks,
Francisco
