hi and thank you all for answering
i have this problem for a while now
i got Dell optiplex 780 Microtower and i have 2 sata connectors and 2 hard drives
i take one of them and install windows 7 on it
and it works just fine
when i try connecting the second drive here is the problem it stops booting and tells me
"missing operating system"
however i did setup my bios at AHCI , And 1st Boot device my boot drive and 2nd the other drive
when i remove the second hard drive it boots just fine
no problems there but when i connect the 2nd HDD again it stuck and the same error "missing operating system" i cleared the CMos and removed the battery
and nothing changes i changed the PSu and the sata cables 3 times and nothing happens
same problem
i am out of ideas and i got so frustrated from this issue and i googled it 10000 times i cant find anything usefull
so please help me .
