Windows 7 - Resizing the Windows 7 partition

Quick question. Easy answer.

Transferring to Ubuntu. Running dual boot system. Need to give Ubunutu more space.

I remember once hearing that resizing a windows partition is dangerous.

Is this true? Will shrinking the C: partition and extending my /home partition in Ubuntu ruin my Windows partition.

No problem, shrinking space will not affect your Windows install.

Thanks.

It's a good idea to defrag the windows partition before you try to shrink it.
You can use the built in Windows defrag.. or 3rd party such as Puran Defrag, Auslogics..

I like Puran and Auslogics because they don't get into super thorough defrag that takes hours. If you have a lot of free space on the partition typically the defrag is done in 1/2 hour or less. That's good enough to push the stuff toward the front of the partition, leaving empty space at the back that you can use in the shrinking.

Edit: also, if you can, any time you play around with partitions it's a good idea to back up your drive to an external. Back in Win2k days I played around with multiple OS using Partition Magic to move stuff around quite a bit and I got away with it. But I got hit with a virus a few years back and had to reinstall. After that I decided to buy some USB drives and have image backups.
