How to go back to windows 7 after installing windows 8


  • I have created a partition on my hard drive and downloaded windows 8 developer preview without loosing any files for windows 7. However every time I restart my PC, I do not have choice to choose between windows 7 or 8?


    Can anyone tell me what to do ?

  • If you installed it the right way, you should see a choice screen between the "Windows Developer Preview" text and the Windows 8 lock screen.

    So, your Windows 8 boots up into the lock screen without providing you with any choice screen for at least a few seconds?

  • Press WindowsKey + R and type "msconfig" and press enter.
    Then navigate to boot, and change the timer option to 30 (that's in seconds ofcourse).

  • The workaround is to put W8 first in the BIOS and add W7 to the W8 BCD.
    Otherwise, wait a few days till the new EasyBCD is avaible.

  • Sorry, i proposed that as the answer without reading further on.

    Does msconfig.exe have two OS's listed? or just the one? If it's just the one then in Windows 8 move the mouse to the bottom left of the screen and click search, then scroll down, click settings and search for 'partition'. The Partition Manager should be the only result - click it and check your partitions. You should have two small partitions and two large partitions - if you only have one large partition then you're in trouble. Also check the capacities of both large partitions and then check the capacity of C:\ to make sure your using the 'newest' partition.

    That won't solve your problem but it should re-assure you that you have/haven't made mistakes in the installation process.

    Windows 8 doesn't seem to be able to access the Windows 7 filesystem on my machine, i would also recommend cold booting into Linux to check your filesystem.

    You should have a look around your BIOS settings first, before trying a repair tool
