I just upgraded my friend's Acer Laptop from Vista to Win7.
By default, Acer has got one hidden partition named PQSERVICE.
Win7 requires an additional 100mb partition upon installation (for the Active & Boot flags).
After installation, I installed Partition Wizard to split up the main HDD but I noticed something strange in the partition setup:
*PQSERVICE (~3.5GB) (Primary)
*System Reserved Space (~100MB) (Active & Boot) (Primary)
*C: ACERDATA (~280GB) (System) (Primary)
* (~3.5GB) (Primary)
As you can see there's an additional nameless partition, which is set as primary and thus preventing me from splitting C. I analyzed the partition using the explore-function in PW, and it seems this one has a similar content as PQSERVICE.
Which of these should be kept as backup? How did this second backup come there?
As a temporary solution, I've set the mysterious partition as logical and split C, creating D as also logical.
Surprisingly, this action speeds up Win7's booting...
Can anyone clarify me the meaning of this partition?
