Actually, before i re installed winows 7 on my ssd, it was running on ide. But it kept crashing so i decided to try and switch to AHCI.
What i did was that i
went into bios to change sata made to AHCI,
with all drives still connected (old hard drive windows 7 also connected) i re installed windows 7 on my ssd.
That's when i got my boot manager problems, when i used to boot into windows 7 on my ssd on IDE.
I never got the boot manager problem when i installed windows 7 on my ssd using IDE.
Anyways, i will try re installing windows 7 on my ssd with all other drives disconnected and see how it goes.
