Problem :
After installing Windows 7 RTM, my computer now skips the boot selection screen and so I am unable to access my Windows 7 RC partition currently.
Is there any way to access it again?
This is not for access to files as I can already access them from the RTM partition.
Solution :
You might try EasyBCD
Using a live Linux CD like Ubuntu, you should be able to access any files and folders on your system, assuming that they haven’t been overwritten.
Assuming you are using Windows still:
XP: right click my computer > propereties > advanced tab > startup and recovery section > settings button and at the top you can select from the various OS installs.
Vista/7: Control panel > system and maintenance > system > left column advanced system settings > startup and recovery section > settings button and at the top you can select from the various OS installs
