@RazvanVL & @UncleGGPlease make sure in the "bios" settings that:
1. Sata MODE is AHCI
2. Make sure your ssd/HDD, where windows is going to be installed (c: drive ) is formated as GPT ( NOT MBR ! )
3. Disable CSM and enable FAST BOOT.
READ HERE for partial info about that.
4. Make sure you've installed Win 8 using "UEFI: xxxxxxxxx" in the boot screen ( pressing ESC immidiatly after you see the ROG icon / as the computer boots up - becuase its fast
🙂 ). The xxx is your dvd/usb device name.
This will ensure that you're going to install windows on a GPT drive ( see note no.3 ) that utilize the UEFI firmware - which in turn enables the ability to boot windows FASTER then the case it is installed on a MBR based HDD/SSD ( which utilized the emulated bios aka enabled CMS mode )
As I understand you've already got windows 8 installed - from experience I can advise you to make a "ghost" image of your C: drive -> clear that drive ( HDD/SSD ) completly -> make it a GPT ( not MBR ) based -> create 3 partitions at MINIMUM on that GPT drive as follows ( the order is IMPORTANT !
😞 efi, MSR, system (=c: drive ) -> Restore the ghost image onto the newly created C: drive -> boot into windows installation disk and perform startup repair -> reboot & you've got windows on a GPT based ssd/hdd.
After you've "ghosted" your windows ( i.e made an image backup of the OS ) and ready to perform the HDD/SSD wipe procedure, its best to boot with windows installation -> open a CMD ( search the web for how to ) -> perform that hole format procedure with DISKPART (
see here for more info ) as follows:
1. look for the desire ssd/hdd number by running the command "List disks"
2. perform the following, Please make note - THIS PROCEDURE WILL
ERASE ALL THE INFO ON THE DRIVE that you'll choose !!!
if I write *** then afterwards text = its explanations NOT commands !
select disk # ***( # = disk number you want to format and convert to GPT
clean
convert gpt
create partition efi size=100
format quick fs=fat32 label="System" ***you can name it EFI or anything else - its the place where the .efi boot files will sit
assign letter="S"
create partition msr size=128 *** this is the 2nd must-have partition - read more about that HERE
create partition primary *** you can specify here with "size=xxx" the size in MiB that you wish c: drive will be ( if you intent on retaining spece for additional future partitions )
format quick fs=ntfs label="Windows" *** here you format the partition as ntfs based 4K blocks ( which is GOOD ! )
assign letter="W" *** it will be C: when you'll boot into windows - don't worry.
