Can OS partition access a dual boot partition if encrypted w/Bitlocker
I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.
If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?
Is there any other reason why this would not be secure? Can a virus write to the BIOS?
Thanks to anyone who can help.
