When installing Windows Vista on my new pc some months ago I made a big mistake. I split the 1TB hd in 2 500Gb partitions. After some months, my system partition (the C-drive where Vista is installed) got full while my second partition (for me called e-drive) wasn’t even half way.
Luckily Vista has a build in partition manager so I tried to enlarge the system partition with some space of the second partition. I failed. The option was greyed out. So I tried Paragon Partition Manager (9.0 professional edition) but also this pay-for software was not able to extend the size of my c-drive.
Then I found a site from a guy named Walker. He describes that a system partition can only be extended if there physically is some space unassigned to a drive directly after the system partition itself.
- So I shrank my e-drive in half. This results in the latter part being available. But this is directly after the e-drive. Not after the c-drive.
- Next step therefore was to create a new partition. I assigned it the letter G.
- I moved all data on e to g
- I removed the e-drive. This resulted in the space getting available directly after the C-drive
- So I extended the system partition with the new created non-assigned space. The option was indeed not greyed out anymore
- I then moved all data on G to somewhere on my C-drive
- Removed the G-drive
- And extended the system-partition also with this unallocated space. Resulting in the complete 1 Tb hard drive as a c-drive!
