Deleted Windows 10 Partion

I have no idea what I'm looking at. I thought i would upgrade from windows 10 to 11 as 10 is no longer supported, I was hoping that the windows update thing would work but for some reason it says my hardware is not up to scratch, well it is. so to cut a very long and frustrating story short, I eventually got an iso file, with all my faffing I didn't do a backup. So I started a new instal and the installation said some thing about deleting a partition, and without thinking said yes, stopped and am now trying to recover said deletion. I was hoping to restore the partition so that windows can boot normally in ver 10 and then carry on with my upgrade. The hard drive is a SSD and the I have run TestDisk and have been presented with the following :
Disk \\.\PhysicalDrive2 - 960 GB / 894 GiB - CHS 116737 255 63

The hard disk (960 GB / 894 GiB) seems too small! (< 2236 GB / 2083 GiB)
Check the hard disk size: HD jumper settings, BIOS detection...
The following partition can't be recovered:

And I realised that I have no idea what I'm looking at, I've tried reading the examples and I just cant put two and two together. It says about checking the jumpers but its a SSD, no jumpers and all I did was delete one of the partitions? any help would be appreciated but also don't want to waste anyone else's time, so if I have to lose the lot and start over, well then that's the price....:(

I'm also trying to learn from the experience on how to do these things but I think my capacity may be a bit limited :lol:

Please post your complete log file.

If you only deleted a partition entry (not the content of the partition) TestDisk should be able to help you.

There are two possible boot process types, MBR and UEFI (using the newer GPT partition table style).

TestDisk asked you which one you are using.
You might be able to find this information in your computer BIOS.

There is an article about recovering partitions:
