Windows 10: Can't find ssd drive anymore after changing disk type to gpt during windows installation

Hi All!Yesterday while I was trying to install windows on a new laptop, I bumped in an error on the partition selection page saying that I couldn't install on my ssd, since the disk type wasn't GPT. So I changed the disk type to GPT using DISKPART cmd line tool. The problem now, is that I can't see the ssd disk anymore when I try to install windows neither in Diskpart using list disk. But in the boot menu, the ssd is still recognized by the system. The only drives that I can see listed are the usb with windows on it mapped on C and another drive with program files and other "Windows C driv

GPT vs MBR for SSD OS Disk ? (win7 install)

I do not understand.

GPT is designed almost exclusively to allow huge arrays. The genesis of windows useable GPT drives goes back to Windows XP x64.

UEFI does not require GPT to boot. UEFI is the BIOS, functionally. It runs before any disk is touched.

As far as booting, stick with MBR on your SSD. There is no 2TB+ SSD on the market, and you're unlikely to have a RAID 0 array that large. Windows 7 defaults to MBR, for so many good reasons it isn't funny.


I haven't the slightest idea about where you linked UEFI and GPT. If you've got a large array as your boot drive you might have to cross this bridge, but given the difficulty I'd stay as far away from it as possible. MBR isn't old, it's still the primary windows drive formatting for a darn good reason.

 

GPT vs MBR for SSD OS Disk ? (win7 install)

If I have UEFI BIOS, I'm going to use GPT. Only reason why I wouldn't is because the drive is shared between new and old computers (MBR has broader compatibility support). I wrote a guide how to install Windows on GPT here:
Installing Windows Vista/7 on a GUID Partition Table

No. Either you install on GPT via EFI boot or you intall MBR via BIOS boot. You can't install Windows and change it later.


Not only does GPT support booting to partitions larger than 2 TB, it also means the computer is booted using EFI which means it has a lot more memory to work with during startup. It should theoretically mean startup is quicker on EFI/GPT than BIOS/MBR.

 

It says I can't install Win10 on m.2 SSD because it's GPT partition type?

I've been going around in circles on this with Disk Management. I formatted the SSD to NTFS, put a 'Simple Volume' on it. Some say to initialize it but that option doesn't come up when I right click it.

So how to I change from this GPT type to whatever I need to load Win10 on it?

I've watched plenty of youtube videos but they don't seem to have this problem. I followed them step by step but the installation stops because of GPT on the SSD.
