Windows 10: Can't see my D: Drive after trying to boot Linux Ubuntu

I got a Flash drive with Linux Ubuntu on and i tried to test it on my computer with my friend. But then i noticed that the system said: "install it on drive" and i didn't wanted, but then my friend accidently pressed the "install it on drive" I don't blame him because it also was a mistake and he tried to press the other option.

Help with dual booting Win 10 and Ubuntu

This is your whole problem. What you should have done is to put GRUB in sdb1 and Windows Manager in sda1 so that Windows Boot Manager is in control.
So what suggested above will not make any difference. GRUB is still in control of booting process.
To fix your problem. You will need to:

1. Move GRUB from sdb to sdb1
   |grub2 - how to move grub boot from one partition to another in linux - Ask Ubuntu
2. Rebuild The Windows Boot Manager ie. create a brand new BCD to boot Windows 10.
3. Once done with steps 1 and 2 above. Windows will not know UBUNTU exists and vice versa.
   Depend on the priority set in the BIOS, it will boot directly into that OS.
   However, you can boot either one from Boot Menu (Using whatever key that your Laptop assigned to: F2, F10....)
   Since I hate Dual Boot and seldom boot into Linux, I will stop here.
   Now, go to step 4 to create dual boot.
4. Use Easy BCD to create an entry for dual boot with UBUNTU. Once done, you should get a nice GUI dual Boot Menu
   and it will boot directly into either Windows or UBUNTU.

Installing Windows 11 on top of Ubuntu/ Linux

I have a Dell Precision 5820 running Ubuntu, and I would like to install a Dual-boot windows. I partitioned the drive (500 gb allocated as free space) in Linux, and then used a usb-boot drive with windows. However, windows doesn't recognize the partition. I've tried many suggested bios settings changes (RAID off, ect.), and also tried using drivers for the SSD which I am trying to install on (It is a samsung NVMe drive), but no luck. Any advice is much appreciated.
