Windows 7: How to HIDE system partitions on Hard drive.

My computer Shows system reserved space as F: and other HP TOOLS as g:, How can i hide that partitions.
TIA

Open Disk Management and set both to have no drive letter, then you won't see them in Explorer.

Drive Letter - Add, Change, or Remove in Windows 7

Did you Clean Reinstall causing Windows 7 to give those partitions letters?

If so test that they will run from boot. If not you can delete and recover their space.

Hopefully you made your HP Recovery disks:

HP Recover Windows 7 Operating System Using HP Recovery - HP Customer Care (United States - English)
Creating a Recovery Disk on a USB Flash Disk - HP technical support (Finland - English)
HP Recov DIsks - make another set

Then will that thing affect BIOS...as the thing was I deleted all my partitions and installed windows from a my old disk (i am also having HP recvy discs but i used my old disk ), then yesterday to go in to bios I installed that HP UEFA kinda update and it created these partitions only after that i was able to go into my BIOS.

So what if after changing the drive letters my system bios goes frenzy.?

Thanking you

i think those were created after i installed that HP UFEA (BIOS or something) ..the thing is these helps me to go into bios settings...

Please explain fully and if possible find a link to the BIOS update you did which you say gave your Recovery and Tools partitions letters.
