- Set UEFI to default in BIOS - Set 'Enable Legacy Option ROM' to True - Set the SATA mode to AHCI - Follow the instructions in this thread to create a UEFI compatible, bootable Windows 7 USB stick - Install Windows 7 on the mSATA drive without any additional SATA harddisk attached - As soon as the Windows 7 installer does its first reboot, shut down the laptop, add an additional SATA harddisk, and power up the laptop.
Has anyone got this to work? I'm wondering if I should give it another try. When I did try the above I received a 'OS not found' error and could not boot into windows.
Any advice or help would be greatly appreciated :)
I installed Win7 on mSATA before Christmas and I have no idea about BIOS version I've got that time, but I have no problem what so ever with installation. Crucial step turning on the AHCI mod, everything else were natural. I Installed system with only mSATA drive just to be sure not lose original instalation data on stock HDD, but after full installation of system, drivers and apps I just plugged in the HDD and it worked well. I deleted all tha partitions and formatted disk.
