    Exclamation Problem Switching to Windows after Ubuntu 11.04 Dual Boot install! (Please read!!)

    Hey guys! I installed ubuntu 11.04 to my Compaq Presario CQ61-402SA (Dual boot with windows 7 Home premium 64-bit, Via a partition) And now I can't get back to my W7! Disk Utility says that it is "unallocated"! Sorry I don't have any other info as-of-now, but ask and I will happily oblige! I don't know what to give, so just ask for ANYTHING (except my bank details and DOB ) It had lot's of important info on it! Sorry for the !s and the urgency, but it's important I get this OS and files back, intact.

    Thx Guys and I hope to see ya'll around.

    Hello. Welcome to the Forums.

    First thing first, Get your LiveCD/USB ready. You are going to need it.
    Using the LiveCD boot your computer and select try. At the Desktop go to http://bootinfoscript.sourceforge.net/
    and download and run the program, instructions are there including how to post the results. This will give us a clue to what went wrong and the best possible way to help you.

    Thank you.

    Boot script shows no windows partition. Did you select install to entire drive, it warns you that you will erase everything on drive. Hope you have a good full windows backup or recovery DVDs that the vendor told you to make from your recovery partition which is also gone.

    Are you able to boot Ubuntu? You have grub & parts of grub legacy in your install and that often causes issues.

    If you had data not backed up and have to try to recover data stop using system as it is overwriting data as you use it. Ubuntu is relatively small compared to windows and some data may be recoverable.

    No, I chose to use a partition to install Ubuntu. But, I DID create a new partition table. I think that is the problem (I just worked that out in the past 10 seconds). If so, How can I recover my data? (as much as I can, anyway)

    PS- Sadly, I don't have any backups or install disks, please don't say I'm f*cked

    Which partition did you have Windows on? In theory it should have been on SDA1 or SDA2. Plus I cannot see an SDA4 in the results text.

    One more command to run
    Code:
    sudo fdisk -l
    the l is a lowercase L not a 1.
    This time select the text in the terminal. In a new reply hit the # icon and paste the text in the tags that appear. This make things easier to read.

    Having read oldfred's post and your further posts. You are probably right with your comment.

    The only chance you have now is using testdisk available here

    Run it from the LiveCD. Do not use the current hard drive at all.

    Hopefully testdisk will find your old partition information and be able to restore it. Doing so might mean you lose your Ubuntu installation which is easy enough to replace as it is a new install.

    If testdisk cannot restore the original partitions your only hope will be photorec (comes with testdisk) to search the hard drive for the old files.

    If it can find any you are going to need another hard drive to write these files to because you cannot write to the drive that is being recovered. And a lot of patience will be needed to go through whatever is found.

    Both of these offer a slim chance at best and no guarantees.

    Greetings,
    Hey there Mobyguy77! I don't want to kick your tail too hard but what planet did you land from that doesn't backup data. Based on my own experience, if you installed over that Windows partition you can kiss your data good bye. Windows never did have a real secure file system to start with so I personally don't think there will be anything to recover. Now that you are here you might as well learn the use Linux and move on. Welcome to Ubuntu! May your nails get shorter and you head get balder.
