I used a combination of research and guides onlince, particularly the tomshardware guide as well as others PLEASE - DESPERATE - ASUS P9X79 - Windows 7 HELP - Motherboards - Motherboards Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs ASUS Official X79 Motherboards Support Thread - Page 23 - [H]ard|Forum
I used UEFI ISO converter to make UEFI bootable DVD, The ISO does NOT have the "extract wim, move, rename bootx64.efi" modification which was in some guides used to force Windows 7 to use GPT, I want to use UEFI boot with MBR, if that's possible, i don't see a problem? The tomshardware guide just doesn't touch this point but that doesn't make it impossible as from other research I've done.
Those guides are old and do not know the existance of this new fixed ISOs.
They also said it's not goot to use DVD + USB for AHCI/RAID RST F6 inject, but I already burned the DVD so I was just going to risk trying with the USB driver
INTEL RSTe F6: http://downloadcenter.intel.com/Deta...+enterprise+f6
ASUS did not have F6 drivers
on their site, or maybe they were in package but they weren't named properly.
- SATA > RAID MODE did not work for me since all of the drivers have been flagged as incompatible and forcing it didn't work, I set it back to AHCI and the C600 AHCI was available as compatible so I applied that.
(lol now I think i forgot to check the F6 drivers in RAID mode, however not sure what was what in asus-sata-drivers)
- Now the installer makes 3 partitions, which doesn't feel like it's using MBR imo, i looked guides on GPT and that was the image, one ESP partition, one Reserved, and the one Main OS parittion.
But the problem is I have passed the CMD option now, i forgot if it is available again, since from CMD you can convert to MBR: Using a Command Line
- At a command prompt, type: diskpart, and then press ENTER.
- At the diskpart prompt, type: list disk, and then press ENTER.
- Record the disk number of the disk that you want to convert to an MBR disk.
- At the diskpart prompt, type: select disk n, and then press ENTER.
- At the diskpart prompt, type: convert mbr, and then press ENTER.
EDIT: however yes, this is what I've recalled now, i've seen on wikipedia that the ESP parition is made because of EFI boot enabled and it has both MBR and GPT, so it's not because of GPT, but still nowhere to check prior install is a pain in the ass.
I just want to be sure or should i just go with it an check after install , if it's not possible then I will it will just take a bit more time which is fine with me since this is the world of PCs and I'm totally okay with that but the point is to save time if possible.
