Windows USB/DVD Download Tool - Home

Did you verify any Checksum value on the ISO?

Sorry I thought you were trying to make your Win 7 a bootable DVD...

 

[Oriasotie Ehis]

i don't get you

 

[Oriasotie Ehis]

so what do i do

 

[RumoredNow]

i don't get you

One of the links I provided were for Win 7 SHA-1 checksums... Your Win 10 ISO won't ever match those.

so what do i do

Make sure you have a valid download...

Do you have an x86 (32 bit) system or a 64 bit system? Did you download the right type of ISO? Have you ran any type of checksum on the ISO to verify it is a clean copy?

This page will give you the SHA-1 values if you click on "show all" and you can copy down the value your file should have. Download Windows 10 Technical Preview ISO - Microsoft Windows

Use any number of freeware tools to verify that the value of your file matches.

Incorrect file size is an indicator of an incomplete download... But even if the file size is correct you need to verify a checksum before you proceed to use an ISO.

Delete the bad copy and download the appropriate Win 10 ISO again. There is no way you are going to magically make it valid.
