    quick question guys ,
    im trying to dual boot windows 7 beside my already installed vista , when i try shrink my c partition to create room for the windows 7 partition , it will only allow me to shrink roughly 2000 MB of the drive even though there is 45% of a 250 GB drive still available .

    they reccomend at least 16GB of free space to install it

    where am i going wrong , im a little confused ,

    thanks in advance

    What are you using to partition your hard drive?

    I assume you're using Vista's partitioner. Is your hard drive fully defraged? I know Vista does this automatically but you should be sure.

    Same thing happened me, so had to use the secondary HDD.

    It says that the Page File or "snapshots" could cause issues with the size you can shrink. I resized the Page File but it had no impact on the space I was allowed to shrink by (110GB free, only allowed to shrink by 500megs).

    yeah guys , im using vista's own partition software , the drive is automatically defraged but im gonna do it again anyway just to be sure , i might try download a different partitioning program and see if that works because i dont have a 2nd drive to install win7 on as im using a laptop,

    sorry for the late reply but im in oz and it was pretty late when i posted.

    gparted live CD is a win for partitioning.

    No need to re-partition your hard drive or shrink current partitions.

    You can install Windows 7 into a virtual hard disk file (vhd).
    The vhd would sit in your current partition and would be seen as a pretty big file. However Windows 7 would see it as two partitions. All explained in the following

    This. I used it at the weekend to put XP, Vista and 7 onto my PC and there was zero problems doing so.

    thanks for all the replies lads,

    just a quick update to finish this thread for people that might have the same problem , i decided to delve away from the vista partitioning tool and download some 3rd party partitioning software called EASUS pro version 3.5 .
    it has worked perfectly for me , partitioning the drive was a breeze , it took maybe 20 mins to partition a 60GB section of my c drive.

    another problem i stumbled upon was during the installation process of windows 7 was when i got to 64% of copying the windows files over , the copying process just froze and would not go any further so i tried an installation for a second time and the same happened.

    so i was thinking its either a corrupt download from microsoft or a disk read error.
    i burned a 2nd copy of the windows 7 iso at the slowest speed that my burner would go which was 2.4x (the last one was burned at 4x ).

    i started the process again and i now have the new windows 7 operating system dual booting beside my vista operating system.

    i must say it looks really good , i have not gotten a chance to give it a good look over as of yet , but so far so good.

    thanks for the help,

    regards,

    dave
