Installing a new SSD and going from NTFS to EUFI

SteveKent · 16 Jul 2022

Hi,

I know this has been asked before, so any link to an answer would be appreciated.

I currently have a Crucial MX500 500 GB formatted to NTFS but want to install a Samsung 980 1 TB PCIe 3.0 (M.2) but using EUFI so I can update to Win 11 if I ever want to.

Hopefully this is possible as I would hate to have to reload Win 10 and all the associated software I have got on the current SSD.

All my data is on one of the HDD drives, with the other HDD being used as a backup.

WIn Version 10.0.19043 Build 19043

I assume your going to do a clean install on the new drive its important to disconnect other drive during the install or files can end up in the wrong place. Uefi has nothing to do with ntfs when set to uefi it still formats ntfs normally.

All you need to do is create the bootable usb from MS and LET it created the usb then boot the pc set the pc to uefi secure boot and tpm on boot the usb and it should go good.
You can then connected other drive when it loaded ok. You may then have a problem as any data will be owned by the SID of the other o/s so you may need to take ownership of folders to access them

ntfs and fat32 are filesystems.

mbr and gpt are partition styles

You would want the nvme disk to be gpt partition style. You would want your nvme os partition to have the ntfs filesystem and the esp partition to have the fat32 filesystem.

Is your crucial sata ssd mbr partition style, or gpt partition style?

if your crucial sata ssd is mbr, you could probably convert it to gpt, then do an os migration to your nvme disk.

if your crucial sata ssd is already gpt, then you could just do the os migration.

Current SSD is MBR, I believe it needs to be GPT to enable the EUFI which Win 11 requires for safe boot.

It's this sentence I am having trouble with as my OS SSD is legacy

To change these settings, you will need to switch the PC boot mode from one enabled as “Legacy” BIOS (also known as “CSM” Mode) to UEFI/BIOS (Unified Extensible Firmware Interface). In some cases, there are options to enable both UEFI and Legacy/CSM. If so, you will need to choose for UEFI to be the first or only option"

How can I change the current SSD to UEFI from Legacy?

If it meets the requirements, you can use mbr2gpt:

I'll print that out and try it.

I tried to convert disk with aomei but it came up with this warning, so I didn't do it.

Your computer is booting from the Data drive (System and active) then transfer the boot sequence to C:
- Create a drive image backup of your MX500 and save on drive 1 or to an external drive (better be safe than sorry)

- With Aomei set C: partition as active.

Shutdown and detach (SATA or power cable) Drive 1 (Data) and Drive 2 (Backup Data) from the MB. Set Boot priority to Drive 0. See it boots.
If it boots normally, run mbr2gpt following the Convert Windows 10 from Legacy BIOS to UEFI without Data Loss tutorial.
Once converted, shutdown and set BIOS as UEFI.
Once booting normally into UEFI, you can install the Samsung 980 and clone the MX500 into the 980.
When cloning put the partitions on this order
- EFI - Fat32 - 100M
- MSR - RAW - 16M
- C: - NTFS
- Recovery - NTFS (try to enlarge the partition to 850M)
Boot from the 980.
Shutdown and attach back Drive 1 (Data) and Drive 2 (Backup Data) from the MB.

Run the following commands in command prompt with admin:

Code:

diskpart
select volume c
active
exit
bcdboot C:\Windows /s C: /f BIOS
exit

Then boot the computer and go into BIOS settings and set Disk 0 as the first disk in the boot priority order. Once you are actually booting the computer from disk 0, then you will be able to run mbr2gpt on it. Right now you are booting from disk 1.
