Hi, I got my new Lenovo Thnkpad P52 Workstation. I'm putting additional M.2 SSD now. I have a 2.5 Spin Drive from factory which have Win10 and as boot disk.
Now, I installed M.2 and want to remove my 2.5 HardDisk completely and keep only M.2 as my Boot Disk. Is it possible ?
Haver anyone tried ? Please share steps ?
What BIOS settings needed to achieve this ?
Is it allowed by Lenovo BIOS/Hardware configuration to use without a 2.5 Disk onboard ?

Lenovo BIOS not accepting my USB drive as a boot disk to re-image a Win10 on the new M.2 disk. I see the new USB disk in the boot order's list but when i select to boot it just bails..no errrs thrown .

How did you install your Windows 10 image on your USB key ? If Secure Boot is enabled, you must have a UEFI / GPT formatted USB boot key.
The best way to do this is to use Rufus to create your bootable USB key.
In Rufus, make sure "Target" is set to UEFI (non CSM)
This will create a UEFI bootable key which should then boot to install Windows 10 properly to your new M.2 drive.

Your advice that the USB drive has to be partitioned to match BIOS boot mode is not quite correct - in my experience.
I only use MBR/FAT32 flash drives to do UEFI installs - on many laptops and PCs - without issues. That includes safe mode.
I understand that Rufus is popular, but it has several (perhaps too many...) options that can lead users astray. For clean Win 10 installs I either use the MS media creation tool, or just open a Win 10 install ISO with Windows Explorer, or an archiving tool like 7zip, and copy the ISO contents to a MBR/FAT32 flash drive. Never had an issue. (so far...)
For a legacy install the flash drive may need to be formatted NTFS and will need a boot loader installed - either via Rufus, or by preparing the drive with diskpart.

Yes, Rufus was somewhat confusing but it is now much better. Download Rufus 3.5
1) Click on the diskette to select your ISO image
2) Change the Target System to UEFI
3) Click Start

Thanks Everyone !
I was able to install Win10 using Windows Media Creation Tool eventually. All trouble was due to wrong way of creating USB Boot disk, i belive now.
