[SOLVED] Can't boot after installing a new mother board

I just installed a new mother board, everything else hardware wise remained the same.

When I go to boot up I get through GRUB just fine, but just after Arch starts to boot I get a message saying that it will wait 10 seconds for something followed by this error;

Unable to determine major/minor number of root device

That is followed by a line with the UUID used with what I presume is my root partition. At this point it drops me to a recovery console which I have no idea what I should do in for this issue.

I rebooted and chose the recovery session option, or whatever it is called in GRUB, and that booted just fine but without network support. Since I wasn't able to look up a solution or do any system updates or anything I stuck a Mint live disc in and rebooted into that which is what I am on right now.

Any help on this would be greatly appreciated.

Boot the fallback image again and regenerate your default mkinitcpio image.

Re: [SOLVED] Can't boot after installing a new mother board

Thank you, that seems to of done the trick.

For those of you who find this thread because of having the same issue, here is the actual command I used to regenerate the images:

mkinitcpio -p linux

Here is a link to the relevant Arch Wiki page on mkinitcpio for those who would like to do further reading on what it does:

Oh, as a side note, that command does need admin privileges to work properly.
