You're incredible the best. I tried some other commands and as I was half way I read the comments where someone said "you f..d up my pc" so I immediately stopped and restarted but when I turned my pc back on I got a microsfot sad face of something was wrong with my pc twice. It finally repaired itself and now you have helped me with this. Thank you so much

Thank you! I tried reading the article to fix this but your video was the only way I could make sense of it. Can't believe they expect us to do this just for an update. I wouldn't have been able to do it without the help of your video here. Cheers! 🤙

i have problem cuz my recovery is on windows reserved and i cant install update there. I tried to move recovery to different, fresh 250mb partition but its stil on windows reserved...dunno if i should just resize windows reserved +250mb and update will go through? also i should not format system reserved as it may have boot data or something important...

I have a disk with 3 partitions; My winRE is on my recovery partition, and there are 2 other partitions that are both labeled primary. Which one do I shrink? I thought we modify the one that winRE is on, so I tried to shrink the recovery partition but it gave me an error saying I can't do that.

Amazing- thank you so much!! I saw on various threads I needed to resize the partitions to fix this issue, but I really appreciate having the video walkthrough on how to do it. It made me feel much more confident about messing around in cmd.😄

[kreiyu]

not sure if your audio cut out half way through, or if you just stopped talking. but thank you for the video. the broken update was messing with the xbox app, but this helped to fix it.

[grimgracious]

Mine says I'm unable to - any reason why? I did run is as admin, but I have multiple partitions listed as well. I chose the ones that said recovery.

MY MAN. I love tutorial videos like this - no noise, flashy intro or affiliate links. Just plain useful info. I just ran this and it worked like a CHARM- thank you so much!!

A side note to anyone who might be having trouble making a new partition: DOUBLE CHECK STEP 5a!! (Make sure you discern between whether or not your drive partition style is set to GPT or MBR. When you are in the diskpart program, run "list disk" and keep an eye out for the table it provides--specifically the "Gpt" column. If there's no asterisk there (in the drive your provisioning), then make sure you don't use the command shown in this video, but follow Step 5.1.ii. ("create partition primary id=27"). I did this exact thing and began following the steps in this video on Step 5.b. and had no problems- hopefully this helps somebody out there :)

When I run the reagentc /enable i get an error that the Windows RE image is not found. When I do the /info my recovery image index is 1 while yours is 0. Is that the problem?

[gamingwitharandomguy]

if i accidentally change my winRE partition from part 3 to part 2 is it a problem or no?

[CHAINSAW]

I did not understand the manual from Microsoft fully until now, problem fixed. Thank you so much!

[csarjr]

i found the instruction, and dont understand .. until i search at youtube and found ur vids, this really save my life.. thanks

[AlexLe-fkzz]

What if I dont have the reserved partition? I have only the system and primary one when ran list part

[nolanmyre]

Thank you for including the website from MS that walks through how to fix the issue.

[xadamdudex]

I've tried to resize the primary partition but for some reason i get an error saying something like the partition will be too small for the system files yet i have well over 100 gb of free space on the C: drive and am only resizing it by the 250 mb in the cmd command .. im puzzled about whats going on ..

[deathwolfz]

after enter format quick fs=ntfs label="Windows RE tools" command i have problem DiskPart has encountered an error: The parameter is incorrect.
See the System Event Log for more information. how to fix it please help me

What to do if this happens? Any tips?
