I have a 256GB mSATA drive now in a 7720 (17R SE) running BIOS version A13. Installed W7x64 on the mSATA - fine - but can only boot the system when the W7 install disk is present (and BIOS in legacy mode). System is booting from mSATA, but will not boot on it's own from BIOS (no W7 DVD in drive and no other HDD in system). Using AHCI mode and both UEFI and Legacy modes won't allow boot. I think I need to enable the BIOS to see and boot from the mSATA drive, but I can see no way of providing access to anything other than Primary/Secondary HDD, removable media, CD/DVD, network...
Any suggestions? Or does it just not work with the BIOS restrictions on the machine?
BTW - I'm REALLY impressed with the boot time into W7 with this! (Just annoyed that I need the W7 CD in the drive in order to get it to start).
Any help will be really appreciated.
