I am trying to load VISTA SP2 to an unallocated partition on my hard drive that already has win 7 installed.
I downloaded the 64 bit SP2 vista install DVD through torrents, and poped it in the DVD drive. Since I have an upgrade product key I did a clean install in the unallocated part of the HD. I did not enter the product key, since I want to do that when I upgrade the same install in order to get the key accepted.
The problem happens when I try to do the upgrade. I get an error that the "active" partition does not have enough space(error 80070070). Well this is not exactly true. When I installed win 7 on the empty drive I noticed that a system reserved partition was created with 100MB and set as active.
It appears that the VISTA upgrade has an issue with this part. since it is set as active, and as a result assumes this 100mb win 7 part. is where it wants to install the upgrade.
Without going into multiple paragraph explanation, lets say I tried to set other partitions as active and it still failed for other reasons.
Has anyone installed vista after win 7 was installed? Does anyone know a way around my problem?
