Do you reformat ssd prior to clean isntall of 10

I do a complete data wipe, format and repartition of the drive. Clean install needs a completely clean drive. IMO.

I disagree. Select Custom Install - delete any partitions listed on the drive you want a clean install to, select the unallocated space and let Windows 10 create the partitions.

Hi there

sorry to labour the point -- I think if you do it this way then if the SSD is an MBR disk then you won't get the UEFI boot of W10.

With Diskpart you can convert the MBR HDD / SSD to GPT before starting any Windows install.

Up to you --these days on modern computers and laptops I prefer having all my HDD's and SSD's as GPT drives.

Note -UEFI is not the same as secure boot which is something else entirely.

You would be mistaken. If the hard drive/SSD has no partitions on it at all, Windows 10 will partition the hard drive/SSD using the partitioning method called for by bios.
