Re: Edit grub to boot different partition of ubuntu?

[J Fields]

So now I have two UUIDs that are the same:
/boot/grub# blkid
/dev/sda1: LABEL="TOSHIBA SYSTEM VOLUME" UUID="E074CBD574CBAD1A" TYPE="ntfs" 
/dev/sda2: LABEL="SQ004585V03" UUID="4A90D31E90D30EF7" TYPE="ntfs" 
/dev/sda4: UUID="85251b80-f37e-4576-832b-fd73013eddbe" SEC_TYPE="ext2" 
TYPE="ext3" 
/dev/sda5: UUID="85251b80-f37e-4576-832b-fd73013eddbe" TYPE="ext3" 
/dev/sda6: UUID="cd3cc320-b49a-4acd-aa37-ae946b5395c3" TYPE="swap"

Another fellow recommended using:
Change UUID see also man pages:
uuidgen
sudo tune2fs /dev/sdaX -U numbergeneratedbyuuidgen
or:
sudo tune2fs -U random /dev/sdaX

I guess I could upgrade to grub2, but wonder if that would help 
get the partition stuff working...
