Doubt regarding partitions.

Need help... This is what i did..

1. I had 4 primary partitions initially. C with 400 GB, F with 25GB, and 2 system partitions (one was 200MB, and other 2GB, recovery partition).

2. I deleted C, created a new partition C with 150GB, remaining 250GB as unallocated space. Installed windows in C

3. With easeus partition master, i thought of creating a new partition with unallocated space. It asked to change one of primary partition to logical. Changed F to logical. Then created a new partition H with 250GB.

4. Everything is working fine.

Doubt is.. if i have to reinstall windows from the start, again, sometime later, and if i do that with a bootable DVD, what will be status of these partitions. can i format and install windows in that new C (with 150GB)? Is there a possibility of files in H (newly created logical partition) deleted? Thanks.

It shouldn't interfere with logical partition. You can even have windows installed on a logical but boot files must be on a primary as far as I know.

No, when installing Windows no single file is affected or deleted. Not even in the partition it's installing to, much less on others. The exception to this is when you explicitly tell the installer to format a partition, then that one is completely deleted for obvious reasons.

thanks...
