Hello: I did a short search on the board as well as a Google search for the topic which I wish to briefly find an answer to and so far I have not been as successful in finding what it is that I am hoping to get. For your convenience the specs for my computer are in the the following: windows 7 home premium with 4 gb ram on a 64 bit OS (Acer aspire). The processer is intel core On my HDD there are 3 Primary drives. One of them being the PQservice drive, the second one being NTFS system reserved and the third being windows 7. As many of you are aware we can only have 3 primary drives on any one HDD. I wish to install another version of windows on the HDD; however, I cannot because of the limitation restriction of only having 3 primary drives. I was wondering how I would be able to do this as the pqservice drive is important to have. Some questions that I would like to pose are listed below: 1. Can the pqservice drive (currently at 15 GB) be converted to a logical drive and still be safely used and functional after subsequent boots of the laptop after it has been converted to a logical drive. Or does it need to remain as a primary drive all the time? 2. If it is possible to convert the pqservice drive to a logical drive ( data will be lost no doubt during the formatting and conversion) after I have booted into windows 7, then copied the contents through using either easus or acronis as examples (or maybe just simple copy/paste?) and still remain booted while in windows. Then after formatting the pqservice drive to logical, recover the pqservice files and folders (from acronis or easus) onto the newly formatted logical drive and then reboot back into windows 7 all the while having the pqservice drive remain usable to the operating system thence? 3. If not possible in converting the pqservice drive to logical (so as to be able to get the previous primary drive now usable for the second windows operating system that I would like to install) because perhaps the pqservice drive needs to remain as a primary partition, then how would it be possible to do so? thanks very much for your assistance.
