Sarcasm is allright, when it comes from people that know where their towel is.
Posting things about this specific topic - judging from the amount of misconceptions you showed in your post - may be a bit premature for you.
You seem like not having digested the basics of booting a mapped .iso, you should try reading CAREFULLY this:
(sticky in the grub4dos Forum)
Let me also remind you what this thread is about:
- it derives form the main "map .iso to (hd32) or (0xFF)" thread (sticky i the grub4dos Forum as well)
- it is about contrasting reports about possibility of booting and installing Windows 7 from it's UNmodified .iso by simply mapping the .iso in grub4dos
Consequently ANY other method is OUT of the topic.
Please let me also remind you that:
- the reports are NOT confirmed, nor documented extensively and the members who reported success with this are NOT experts in using grub4dos nor usual members of the board, with all due respect to them and to their work and reports they are less reliable than reports from an expert member like Steve6375
- the method, in theory, CANNOT work (or at least cannot without additional files - which means that something needs to be modified inside the .iso or outside it)
If you have ANY second hand report abot this EXACT method (working or not working) this is NOT the place to discuss it.
If you have ANY, first or second hand, report about ANY other method BUT the one we ARE talking about, AGAIN this is not the right place to discuss it.
ONLY if you, yourself, tested this EXACT method and are wishing to report what happened describing FULLY and with the most DETAILS the hardware you tested it AND if it was UNsuccessful (likely) or successful (UNlikely), this would be the right place to post your report and your experience.
Installing Windows 7 from pendrive is PERFECTLY possible, and there are several tutorials/apps about how to do it.
An "advanced" one is written by Steve6375:
Another "advanced" one is by Ilko:
Besides the original (classical) MS tool/method, illustrated by Jamal here:
You are expected to be familiar with the concepts in the above mentioned threads and do your own experiments in order to be able to contribute....
Hot water and wheel have already been invented, see also the post by Wonko the Sane on one of the threads you mentioned:
Obviously we are all drooling at the idea of hotter water and rounder wheels, but we do know how known hot water ad common wheels are made.
