[SOLVED] windows 8 + windows 7 dual boot not working

post #1 of 27
Thread Starter 
hello, so i just downloaded Windows 8 Developer Preview with developer tools. so i installed it on a different partition and it installed without any problems. but when my computer restarts after the installation, it just boots into windows 7 instead of windows 8 boot manager... is it that the w8 boot manager wasn't installed, or something else??? please help
thanks +rep for good answers

Hmm, it should've modified the MBR.... Does the new partition show up in my computer?

Just as a test, see if you change the start up and recovery

Here are steps:
here

And try setting windows 8 as the default for now. See if that forces it to boot into windows 8.

99% sure when you install Windows 8 it messes with the boot settings and makes Windows 7 unbootable. Just have to use some VMware, or a seperate HDD bud.
