Hi There,

Thanks for your reply - I managed to get the MMTool elsewhere, but not on the TweakTown forums though. I modded the latest bios for my laptop named G771JWAS.211 (with the small compressed nvme - the only one that fitted) and tryed to use WinFlash (from Asus) to flash the BIOS. It gave me a warning stating that the BIOS was older that the currently installed. I found on a forum that I could launch WinFlash with /nodate and so I did. However this time it complained that the BIOS file is invalid. Am I missing something or should I use a completely different BIOS Flash utility to flash the modded BIOS.

Thanks in advance

I have also tryed to use Easy Flash (from within the BIOS), but the modded BIOS has the same build date that the current one - so EasyFlash doesn't update (gives an error about the date). Is it possible to change the build date of the modded BIOS?

Hi, i'm trying to run ADATA Sx8200 on asrock z68 extreme 4.
I modded bios (succesfully probably, coz i have PATA in boot options), i had disable secure boot, csm, fast boot, unplugged all other disc, and i have problen when i'm install os(win10) from pendrive in uefi mode. I can choose particion, windows creating more own particion, installation was running but when installation reboot, i had error about no disc to boot.

I tried marvel sata controller off, floppy controller on.
Disc is conected to pciex x16 via adapter. Anyone had same problem?

I tried your options and still same error, after reboot installing os it doesnt see any bootable device.

I find probably my problem. In os istallation i got 1 disc (nvme) but name as "disc 2".
In repair mode when i select command line, it start "x:\" looks like it is X particion?

Else when i choose repair while start, i have error with information logs are in
"D:\windows\system32\logfiles...."
So its seems like windows labelling main particion as D. I have unplugged all disc, only nvme+bootable pendrive are plugged.

D particion is probably the reason why windows cant start after reboot instalation. Still dont know how to solve this. In meanwhile i tried another version of windows (w10 clear version) and still same.

After os installation reboot, bios again run bootable pendrive and again first step od installation. When i remove pendrive before reboot, error no bootable device after reboot.

@fernando
Link works for me, i add it here again.

Also I checked easyBCD and i dont really know what i should do with this program.

I didnt try another flash drive, but i will.
I checked all requirments from first post.

In 'chose partition' I mean I can create partition from empty nvme drive (eg. 200gb from 1tb disc) and OS installer create all neccessery partition (im my case create 4 partition). After that, installation will reboot and no boot device. After this installation partitions look like on picture. Label C is pendrive with OS :/


E: I also make the partition 'recovery' was labelling C and still no boot. Secure rom disable, fast boot disable, checked with CSM on and off. Still same problem :(

E2: easyBCD listed double nvme disc as on screen. Cant understand it.
