You can also run defrag in this step in the repair environment, it might work better than if windows is running on the drive. then run "chkdsk C: /f /r" until no errors. You can do this in cmd/terminal but there's an extra option on the del command like "del /a:s c:pagefile.sys" to let it view system files, not sure if that's it, ( )), hibernation, kernel error logging, run cleanup wizard, system restore, run cmd defrag ( ) like "defrag C: /x /h /m" ) Make a safety net: Ubuntu and TestDisk (dont f up, somehow I never did), and have a USB Microsoft Windows Install.ĭelete and disable all the stuff in windows (disable pagefile and restart and manually delete "c:pagefile.sys" (must enable view system files, folder options->view->uncheck. SUGGESTED PROCCESS (probably inefficient and likely wrong):Ġ. My first time took a few hours/overnight and I came back and it had failed with an error and ran it again and it took like 5 minutes and succeeded. If chkdsk fails, try it again, it may only take a few minutes. Then (this is where it worked for me), run chkdsk :C /f /r (or make sure it's the right disk name, mine was I: and not C:) in a repair environment (you need a thumb drive) and leave it for a few hours (my partition was probably so broken because of so many other issues and attempts without knowing what I was doing). SO - defrag your drive and /x to move empty space to the end of the drive.
#Shrink a dink install
I deleted all the windows safety files, kernal error logging, deleted the pagefile, turned off hibernation, turned off recovery (omg install ubuntu, make a copy, and get testdisk!), and was still just getting "you're trying to shrink the volume too much!" errors and couldnt even make the 100mb of space to make an EFI partition. I ran admin terminal defrag /x and was still having issues.
#Shrink a dink Offline
If you follow them and still run into the same wall, THIS GUIDE IS FOR YOU! The missing link for me was to run chkdsk in an offline environment. First of all, most of the guides out there are actually on the mark in helping but forget a few possible steps.
#Shrink a dink download
Another tip I suggest is to get the program "TestDisk" on Ubuntu just in case you f yourself and mess up your partition table or boot sector (TestDisk is open source and very well documented cryptography program - please please please dont download that AEOMI or Easyus or any of that garbage, I swear it's all the same company throwing out posts and up-voting their answers even on answers.microsoft to promote their suuuuper sketchy program that broke my install more than once, just skip those and get TestDisk in Ubuntu "sudo apt-get install testdisk" then just "testdisk" and that'll open a text gui in terminal, use their online documentation for tuts and stuff, its really good).Īnyway, if you ever try to run mbr2gpt, windows Disk Management, or diskpart to SHRINK your active C partition and it just tells you to f-off, it's likely a few things could be happening. I used "Disks" in Ubuntu and hit the three little dots in the top right corner of that to made image copies of my actual boot disk on a separate disk so I wouldn't totally screw myself (highly suggest, even though this is essentially copying 1TB+ just for security). I eventually made myself a very small (20gb) Ubuntu install on a separate disk so that I could easily do some recovery tools and experiment. I wanted to just use Microsoft's MBR2GPT.exe tool ( ) (which is amazing) to migrate and it all sounded easy but was not. I've been running MBR and BIOS boot now for a while, and was dual booting Ubuntu and broke some stuff (windows) more than a few times. This post is long, frantic, somewhat disjointed, I'm very tired and running on caffeine, the most important points are here and weirdly super rare and hard to find elsewhere, I'm sorry. Ok, so I figured it out, at least for me.
