Hi!

Good day to all!

I just recently installed a m.2 PCIe SSD (Intel 600p 256GB) to my system to serve as my boot drive (Win 10). I also have 2 SATA HDDs (500GB Toshiba - Windows 7 and 2TB Seagate - Windows 10) which has served as boot drives for me in the past (didn't have the time to reformat them) and just have them as extra storage for my PC.

My problem now is that whenever I set the m.2 as the first boot priority, during boot up the OS from my other drives pops up instead. I have to manually select the m.2 OS from the available boot drives for it to boot up. I disabled the other boot drives in the boot priorities but after reset, they get back again in the list. When I disconnect the SATA HDDs, the m.2 alone doesn't boot up. I spent a whole afternoon playing with the setttings on my BIOS (setting the SATA mode of the drives to AHCI and to RAID, switch priority bandwidths between m.2 or PCIe devices, deleted the other OSs thru msconfig, etc.). I'm currently trying to clean format the other drives to remove the OSs, I'll update this as soon as I finish that.

Please advise on what may I do yet..

Thank you very much!
