They can create a Windows 10 recovery disk on another computer and use it to boot their troubled PC. Note that you can't use a recovery disk made for Windows 8 to recover/troubleshoot/repair a Windows 10 PC.

How to Create a System Repair Disc in Windows 10?

Step 2: Now, write 'recovery drive' in the Search Box. Then, from the list of results, choose 'Create a recovery drive'.
Step 3: A Window will open. You have to check 'Back up system files to the recovery drive' and click on 'Next'.
Step 4: Now, you should select the USB flash drive, then click on 'Next' to continue.
Step 5: On the next screen, you have to click on 'Create' to begin the process.

Well, it's a technical task, errors can occur any time and you can't neglect them. Of course, you can resolve them.
Burn recovery drive ISO to your USB drive
When Windows fails to create the recovery drive and gives the error 'We can't create the recovery drive', the first thing you should do is check whether you have properly connected the USB drive, and is it identifiable by Windows?
If this isn't the problem, you should simply download the ISO file of Windows 10 recovery disk and burn it on your CD/DVD or USB drive.
Fix the problem we can't create a recovery drive
This problem occurs when the Windows recovery environment gets disabled. You can open an elevated Command Prompt and run the 'reagentc/info' command in it.

Step 1: If there isn't any Recovery folder in C drive, make one. Now, make another folder in that Recovery folder and name it WindowsRE. Note that the default state of the Recovery folder is hidden. So, you should type 'show hidden files' in the Search Box. File Explorer will open. Now, click on the checkbox before Show hidden files, folders, and drives option and uncheck Hide protected operating system files(Recommended) option.
Step 2: From this to Step No. 4, you will be creating Winre.win file (however, if you already have a backup of that file or if it can be copied from some other Windows 10 PC, move directly to Step No. 5). Mount Windows 10 installation ISO file as a virtual drive and open it.
Step 3: Go to the Source folder and find Install.wim file. Copy the location path of this file.
Step 4: Now, you should type the following command in the elevated cmd (Command Prompt):
dism /mount-wim /wimfile:[just copied path of install.wim file] /index:2 /mountdir:[the location path where you want the mounted file to be saved]
Thus, the command will be something like this: dism /mount-wim /wimfile:'F:windows 10 ISOsourcesinstall.wim' /index:2 /mountdir:D:mount_image_file
Step 5: Go to the location path you mentioned in the previous step and find out Winre.wim file. Then, copy this file to the location C:RecoveryWindowsRE.
Step 6: Finally, type the command 'Reagentc /setreimage /path C:RecoveryWindowsRE' (don't use quotes).
