I have 350gb free of space, I don't know what to do.

I created an ISO and I virtually mounted it to my computer and I get this error. I tried clicking and dragging all the files into a folder onto my computer and re-attempted but to no avail. I've tried "running as administrator" but still no luck. 

Thank you for any support you can provide. I'm running Windows 8.1 right now.

Bingbing,

How you create the ISO here?

Windows 10 now is available for download through the following website:

Download Windows 10

https://www.microsoft.com/en-us/software-download/windows10

Besides, please make sure that we have more than 20 GB free space available on the system drive.

Dismount the ISO that you mounted earlier, then run the disk cleanup, after that, use the newly downlaoded media to start the upgrade again.

I'm getting the same error. I have an SSD as my boot drive (currently Win 7 64bit).  I've tried all of the following:

1) Increasing the System Reserve partition from 100mb to 600mb.

2) Removing all drives but the boot drive.

3) Removing all USB devices

4) Installing from Windows Update, the MediaCreationToolx64.exe and from a DVD.

5) Deleted the $WIndows-BT and $Windows-WS folders.

The last two install methods provide more info than the Windows Update install, but all fail. I get the dreaded "We can't tell if your PC has enough space to continue installing windows 10." 

I have 85gb free on my SSD boot drive.

I'm giving up for now - at least until a new installation program is created that doesn't have these issues.

The install needs a command-line option to ignore the disk-space size check! 

UPDATE!!

I found the problem. I booted with the Windows 7 DVD and selected to "Repair". I was going to run the BOOTREC.EXE command-line prompt program to repair the boot record, but didn't even need to. The software indicated there was something wrong with my boot record and asked to repair it - I responded in the affirmative. Once I did that, I was able to install Windows 10 (installing as I type this). One other thing I did, was run MSCONFIG.EXE and choose a "selective boot" and disabled all non-microsoft services and all apps. I rebooted and ran the install.

Hi Bert,

Thanks for the update and sharing.
