Windows 10: How to resize C: partition

Thanks for all the suggestions. I think I may have actually made a USB recovery stick before now that it's mentioned. I'll have to check. Otherwise it's easy enough to make another.

 

Only problem with usb recovery drives is they become obsolete each time there is a build upgrade. If you are unsure if you made one since 10586 came out, you should make a new one (and again when Redstone comes out).

 

My suggestion to you is to leave everything as is except shrink D: and add to C:.
Your PC came with a customized partitions layout from ASUS so those Recovery partitions might have contained code that would allow you to roll back to the factory image. If you delete the Recovery partition, Windows will still be running but will break the ability to recover unless you don't plan to use this option.

 

It's true that you can reorder and resize partitions with MR but as mentioned there is a partition in the way.
What needs to be done is to merge the partitions and the only way I know how to do that right now is the paid version of Aomei Partition Manager: You can check it out yourself: I tried the free version once and went through the procedure to merge a couple of partitions and it showed how it would go even though there was what I call an intervening partition but then it reported the paid version was necessary.

EDIT: I made the mistake of posting before realizing there was a page 2 of excellent information
topgundcp your to shrink appropriate partitions is an excellent one: thank you.

FYI, there's different way to re-arrange partitions. Macrium Free can also do it as posted here:

@ cereberus "Only problem with usb recovery drives is they become obsolete each time there is a build upgrade"
That is what I do. I look at that as I do creating system image backups.

 

You could copy the 21.14 GB (Recovery Partition to an thumb drive (it's probably the OEM Factory recovery for Win81.)
After a successful copy - delete that partition
Then move and resize (-100 GB) Data ( D: ) to the right
Then move the 350 MB partition to the right
Finally expand C: into the 121.14 GB space

But a question looms ... What are you storing on C: ????
Win10 doesn't take up much room - fully loaded with my favorites programs, my machines, only consume between 25 -> 40 GB
All of my data is stored on another partition.

You might want to run some cleanup utilities

Restart your machine in case there are any system operations pending

Click here to download Old Timer-TFC.
>> save the application to your Desktop.
Old Timer-TFC is a standalone application, there is no install.

!!!!! Save your work and close all open windows.
TFC will close ALL open programs including your browser!

Right click, run as administrator TFC

Click the Start button to begin the cleaning up temporary files and folders.
!!!!! Do not work on other things while TFC is running - most applications use some sort of temporary files. Just let TFC run by itself on the machine until it completes.

*Busted Restart your machine immediately after TFC completes.

Open and Use Extended Disk Cleanup

I select all items and then press OK. You might want to keep the previous Windows - that's up to you, but it does consume a lot of space. If you delete the previous Windows, you will NOT be able to roll back - if you upgraded more than 30 days ago, that caution does not apply.

Delete System Restore Points in CCleaner

You can also use cCleaner to remove files that are no longer needed

 

I followed the video and used Partition Magic it worked perfectly with one small difference. It said my D: drive was in use so it had to restart and it handled everything in a DOS-like GUI, then restarted and it was done. It also took longer of course, maybe an hour.

 

Great. I am glad we could help.
Yes, It is normal to take a while depending on how much data you had in D: drive and also normal if your D: drive somehow being used. My video only demonstrated how things is done and my D: drive was empty, that's why you saw it done so fast.
Bill (@Slartybart) also gives good advice to further clean up your C: Drive to keep it as small as possible. Make it easier to back up/restore in case things go wrong. Also, try to have all your data stored in D: drive is good in case your PC becomes unbootable then you won't worry about losing data.
