Mageia 4 fresh install won't boot.
This is probably an easy one but Grub Legacy tells me that my new Mageia 4 install file system is unknown and when I'm booted to Mageia 1 it won't mount the partition I installed 4 on. Mageia's installer offers to install grub 1 so I'm confused of what the problem is.

Thanks in advance!

To clarify so we understand the situation, did you have Mageia 1 installed and just installed Mageia 4?
Are you trying to boot with Grub Legacy from Mageia 1?
What does your menu.lst entry for Mageia 4 look like? Have you tried chainloading it?


when I'm booted to Mageia 1 it won't mount the partition I installed 4 on
Post the command you use to mount and also what the output is when it fails.

I manually boot with grub legacy. I don't have grub installed on a partition shared with a O.S. I'm looking for the mount option which tries all files systems right now since I don't know the file system mageia 4 uses.


[root@localhost kbs]# mount -t btrsf /dev/sdb7 /media
mount: unknown filesystem type 'btrsf'
Edit: 2

[root@localhost kbs]# mount /dev/sdb7 /media
mount: wrong fs type, bad option, bad superblock on /dev/sdb7,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

If you have parted installed, the command below should show filesystem type for all partitions on sda:


parted /dev/sda print all

FYI the file system type is btrfs not btrsf...

You can also try:
file -s /dev/sdb7

I reinstalled and formated the partition ext3 but I got a lot of boot errors. Grub legacy did boot it. Could the boot errors be because of the file system type? The tools/commands on Mageia 1 will not mount the btrfs file system. Mageia's disk tool reads it as btrfs but will not mount it. Grub says it is of 'unknown' type. I'm going to burn a grub 2 boot cd and see if it will boot mageia 4 with the btrfs file system. :hattip: Thanks for the nifty command!

[root@localhost kbs]# file -s /dev/sdb7
/dev/sdb7: BTRFS Filesystem sectorsize 4096, nodesize 16384, leafsize 16384)
