Hello there,

i need some guidance on how to fix an issue with diskpart (i hope).

My UEFI controlled GPT Windows crashed due to tweaking my ram. Windows updates may have occured before that. I don't know.

The real OS Partition on my ssd is not c: drive anymore. Instead it tries to start win from a 500mb c: partition.

With a windows usb stick i could not fix the issue.

But i could take this screenshot after trying to find a driver:



with diskpart my only m.2 ssd looks like this:



choosing disk 0 reveals:


My issue is that in my Asus/Apex xi/ Bios the ssd will show up only as one entry:

Windos Boot Manager - samsung evo // and that entry is mapped to the wrong partition i believe

Somehow C: drive is mapped to partition 1 or 3, instead of my OS on partition 2

Is this fixable via diskpart ?

My Bios settings:

CSM: disabled

OS Type: windows uefi os

Fast boot: disabled (usually enabled)

Sata Controller(s): enabled

Sata Modus: Intel RST Premium with intel optane / i don' have optane btw

M.2_2 PCIE Storage RAID Support: RTS controled

Native Ami nvme driver enabled

Thanks in advance

Best Regards

Carlyle
