I thought Id drop in a link to this ,
I gave it a try the last couple of days ,
Was a little tricky formating the drive and installing the iso , but once I got beyond that it works very nicely .
It contains a suite of great free tools , like drive imaging , data recovery, partition management and repair.
As was the case here I had a HDdrive from a laptop that had a hardware error and wasnt ever going to boot again , the disk wasnt readable in windows , even though it was a Windows OS on the drive .
with the Hiren's PE environment and the tools you can get back access to unreadable Windows GPT partitions , although its only Windows XP that correctly flagged the drive format , later windows continually nagging me to format the drive for use , which of course you never want to do in a data recovery situation .
I used Hiren's CD boot disk years ago ,it was a very handy set of tools ,
this new version is based on Win 10 , without all the microsoft in your face garbage the OS comes pre-loaded with . The drive image comes to just under 3GB total ,
It seems to have the capabillity to run many basic windows tasks without all the fuss ,
