I have an old Vista laptop that I partitioned and installed Ubuntu on, with dual-boot. I've now decided to switch entirely to Ubuntu. What's the best way to achieve this?
My current partitions:
+-------+--------------------+---------------+------------------------------+
| WinRE | C: (dual bootable) | D: | Extended |
| | | +-----------+------------------+
| | | + Ubuntu | Swap |
+-------+--------------------+---------------+-----------+------------------+
I'd like to change this to:
+-------+-------------------------------------------------------------------+
| WinRE | Extended |
| +------------------------------------------------+------------------+
| | Ubuntu (bootable) | Swap |
+-------+------------------------------------------------+------------------+
(I'd like to keep the Windows Recovery partition in case I ever want to sell the laptop).
I'm not sure whether the Ubuntu partition currently has a boot-loader on it. I also don't want to lose my Ubuntu installation/data. (I'm happy to trash the Windows partitions completely - I have backed everything up from those).
Update: Having checked my bootloader, I've deleted the Windows partitions and I now have free space. Unfortunately it looks like I can't resize the existing / (root) partition because it's mounted. Can I get around this, or do I have to re-install?
