mike13 Posted July 4, 2015 Share Posted July 4, 2015 I have a test computer that had Windows 7 on it. I am using it to get all the Windows 10 downloads, because I do not want to mess up my main computer. Anyway, over 30 Gig of space is taken up so far, and all I have on it is Windows 10, and Office 2016 (Trial). I did the disc cleanups and even removed all prior installations of Windows 10, but there is still over 30 Gig of space used up. I know if I install 10162 from an ISO file, I will get the chance to do a clean install. I even tried that with another release of Windows 10, but I do not believe it removes everything. Anyway, this is my question. Can I completely wipe my hard drive with another program called Wipe Drive Pro, and then install Windows 10 #10162 from a ISO file, or will it look for a valid operating system like Windows 7 or 8. 8.1 Windows 10 should only take about 4 Gig of space, not nearly 30 Gig.

kaljukass Posted July 4, 2015 Share Posted July 4, 2015 Of course you can wipe, but do not recommend wipe the drive, however, wipe partition. Where did you take that Windows 10 uses only 4GB - this is the volume, if you have an ISO file, after installation the volume is much-much higher. Windows 10 has not yet been released, why these weird meantime versions are needed? You do not do anything (read: cannot do anything) with them.

mike13 Posted July 4, 2015 Author Share Posted July 4, 2015 kaljukass...Thanks for the reply. OK, so if Windows 10 has a Volume of 4 Gig, what would that equal after installation...about. 5 Gig, 10 Gig, 15 Gig ?? Thanks, Mike Link to comment Share on other sites More sharing options...

Thanks, MikeWindows 8.2 10 should have - more or less - the same hard disk space requirements as 8.1, i.e. between 16 and 20 Gb for a normal installation (wich BTW is more or less the same amount of space needed for Vista, Vista SP1, Vista SP 2, Vista SP3 WIndows 7 and windows 8:https://support.microsoft.com/en-us/kb/919183http://windows.microsoft.com/en-us/windows7/products/system-requirementshttp://windows.microsoft.com/en-us/windows-8/system-requirements When the final version will be released, the new mechanism that is replacing wimboot:http://www.howtogeek.com/196416/wimboot-explained-how-windows-can-now-fit-on-a-tiny-16-gb-drive/ most probably will allow to make it much smaller (do not expect miracles, possibly a couple of Gb saved):https://www.thurrott.com/windows/windows-10/2062/microsoft-explains-os-compression-in-windows-10cannot say if such mechanism is already available in these beta's . jaclaz Edited July 4, 2015 by jaclaz Link to comment Share on other sites More sharing options...

NoelC Posted July 8, 2015 Share Posted July 8, 2015 (edited) I did a clean install a few weeks ago from the build 10130 ISO and it was a bit under 13 GB. -Noel Edited July 8, 2015 by NoelC Link to comment Share on other sites More sharing options...
