How do I remove lines from GRUB that no longer work?

[firenice03]

[size=1em][member=37281]Von Kirkus[/member] [/size][size=1em]I would update grub without the backup connected - hence why the sdb showed up and if there are boot partitions on it it most likely will add.. [/size]

[size=1em]Assuming the partitions are as follows... [/size]

Code:

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 223.6G  0 disk                  USED FOR ?? ??
├─sda1   8:1    0   259M  0 part /boot/efi        Win/LL Boot Part
├─sda2   8:2    0  75.3G  0 part                  ?? - Win ??
├─sda3   8:3    0  19.6G  0 part                  ?? - Win ??
├─sda4   8:4    0    26G  0 part                  LL4.8 root not working
├─sda5   8:5    0     1M  0 part                  small part - ??
├─sda6   8:6    0   513M  0 part                  small part - ??
├─sda7   8:7    0  10.8G  0 part                  LL5.x root not working
└─sda8   8:8    0  91.2G  0 part /                LL5.x Root WORKING

It looks like you had windows, LL4.x and LL5.x all installed at one/sometime.. Were these installed to the new disk (SSD) or copied from the old?
I would say both sda4 and sda7 could be deleted/removed - these are none working partitions...
Perhaps LL4 worked at one time, maybe was pooched during an attempted install, perhaps same with sda7 or realized it was too small for needs... none the less they no longer work and are not needed (you'll re-coop the space)

sda1/2/3 I assume are all Windows... Boot/C:/Recovery-Image partitions... I would leave these as is..
You have both Win and LL booting from sda1 - this is ok... .... .....

sda5/6 - are small, not sure exactly sure why created perhaps these are the 2 you tried create?? where during install sda7/8 where created....

So and I don't think its too big an issue... But you can typically only have 4 primary partitions per disk..
Having 8, I'm assuming 4 are extended partitions - like I say I don't think it'll be a big deal but....


Overall... sda4/5/6/7 should be able to be removed/recovered...
**Check to ensure there is not any data or files that are needed on these partitions (thou sounds like you have back ups )
Once you have confirmed no data and disks are as I mentioned and not in or for use; Windows etc... You should be able to clean/remove those partitions.
**Do this with out the backup connected


Then run grub update and reboot.. you should be left with Ubuntu (LL5.x)  -- Advanced  -- and Windows
