virtual drive too small

[Sebastian42]

In the hope of upgrading Win7 Ultimate to Win10, I downloaded a Windows.ISO to mount with Win.ISO so that I could access the SetUp file in the WINDOWS.ISO. I do not remember being offered an option of WHERE to mount the ISO, and in the event it was on (virtual drive ?) E:\ I clicked the SetUp.exe and was told that the destination was too small - well, I did not want it installed on E:\ anyway - I wanted it on C:\
The next time I tried to progress my aim, nowhere in File Manager or Disk Manager could I find the E:\ - so I had no chance to copy the ISO content to C:\ where presumably, there would be enough room for an install.
The process made the Windows.ISO disappear, so unless can find E:\, I will have to download the large Windows.ISO again. As an added difficulty, when I run Win.ISO now, it no longer opens the original window that had the MOUNT option - instead, it offers ONLY to 'burn-to-disc'. I would appreciate advice to salvage THIS situation, as distinct from advice to do the upgrade in a different way.

You need to boot from a Win 7 ISO in order to use it to install so mounting it isn't going to work. You need to burn a disk from it and then boot from the disk or you could create a virtual machine and then have it boot from the ISO.

If you goto MS site you dont need to mount any iso just hit upgrade and it will download and upgrade Download Windows 10

All three suggestions are ALTERNATIVE methods. I was hoping to get help with the method I outlined. The reason I have confidence in it, is because I have already upgraded Win10 that way. But UNlike W10, w7 does not provide for direct mounting, that is why I used Win.ISO - and at first attempt it appeared to work - except that the mounting was to a (virtual ?) drive that was too small itself, and I could not locate it.
