Install Both Vista & Win 7 from one USB
Having windowses all together is easy process except vista and win 7,
together (I mean the hard part of story is that we can have just one
of windowses vista or win 7 in our media).
Any way i have found a way to do this by USB Flash Drive.This is begining
and hope other friends will work more and this proccess will be easy too.
1.For this project you will need "grub4dos" and "grubinst-bin-w32" files.
I suppose that you have saved them some where in your computer.
2.In This Tutor i used windowses below:
Windows 7 Ultimate Build 7100 (2.4GB)
Windows vista home lite (665M)
1.Make 2 primery partitions in your USB Flash Drive.(In this tutor i am not
going to descibe how to partition USB Flash Drive,If you do not know ,place
notes i will tell how to do that).
2.Make first partition less than 2048M and format that in "FAT" system.
3.Format 2nd (primery) partition as "NTFS" and also make active this partition.
(Note that as i know you can make up to 4 primery partitions on your USB).
4.Plugin your partitioned usb flash drive to computer,and run "grubinst_gui.exe"
then in"Device Name" section select Disk.
Now choose your UFD (be sure that you have selected your UFD and not your
HD) and push the "Install" button, and after reading in the related Command
Prompt press enter.
5.Copy "grldr" and "menu.lst" from Grub directory to the root of the 1st partition.
6.Copy contents of Vista CD (Vista lite in this example) to partition one of your
usb flash drive.
7.Copy contents of Windows 7 DVD (Windows 7 Ultimate Build 7100 in this example) to partition 2 of your usb flash drive.
8.Open "menu.lst" file (in root of your usb),delete all contents of that ,then add
lines below to it and save:
color black/cyan yellow/cyan timeout 30 default 0 title Vista setup find --set-root /bootmgr chainloader (hd0,0)/bootmgr title Windows 7 setup unhide (hd0,1) hide (hd0,0) root (hd0,1) chainloader /bootmgr
Thates All ,now you can boot by your usb flash and can select vista or win 7 to install.
I have tested was ok,but please pay attention to notes below:
1.You can add other tools to this usb ,just you should add proper command in "menu.lst".
2.You can have more primery partitions in your usb and put other OS's as xp sp2 and sp3
on them,just you should add proper command in "menu.lst".
3.The 1st 10 minutes of setup process is a little bit slow.
4.when installing windows 7 i encounterd by error below:
"A required CD/DVD drive device is missing ......."
This is an error that many of users see when installing windows 7
any way i thought may be it needs USB driver so i gave the address of inf
file (cfadisk.inf) that i used for partitioning usb flash drive.first time it
did not accept but when i addressed that for 2nd time ,setup accepted.
So may be you will need to put your usb drivers some where in your usb
(note that when installing the usb drive is shown as drivr X:)
