Windows 10: How to increase the System Reserved Partition size

I don't know why it didn't work on your other Win computer, but, I always use my MR from my boot disk. I would think you would want to create at least one "Rescue Media" disk anyhow?? If someday, you couldn't access your C-drive, your only choice would be the rescue media disk, to fix or to restore a previous disk image. MR gives you 2 ways to make this disk, DVD or USB whichever choice is best for you. I have to make both, as 1 of my computers will not boot from any USB port, while my newer computer does both, with no problem.
Just my opinion on this......didn't mean to butt in.....*Smile

 

If a disk you are working on currently running Windows then no software would allow you to do it, this includes Macrium, Mini Tool, AOMEI Partition Assistant, EASUS etc.... You must do it offline. When you boot up your PC using Recovery disk or Macrium Rescue disk, the PE environment loaded into RAM and run from there so all HD/SSD are available for you to modify the disk layout. In the first case, you did restore to another disk then that's perfectly OK since that disk was not running Windows.

 

I have already created rescue CD but I want to know why this error came on one PC and not on another.

 

Well topgdcp just explained to you why.....maybe you missed his post??

 

Oh my God, I missed your post and yes I forgot that earlier I had restored to another disk. But you are marvellous, you noticed that.

 

Thanks for pointing that I missed his post where answer to my query was cleared.

 

Now I used the Win PE boot menu which went very smooth.

 

Very glad everything worked out sam!!! thanks for posting your results back too. Congrats, nice job. *Smile
