Installing Win7 from USB requires driver (using YUMI)?

SIW2 · 11 Aug 2014

Which setup asks for drivers?

If it is windows setup, it gives that message if it can't find install.wim.That might be the problem.

It may not be finding it, or it may not be recognising it.

i got this partially working on YUMI but when you go to install windows from the stick it dont work, while ago when i tried so cant remember the error it threw...could of possibly asked for driver

if i recall I was told to use Grub and unlisted ISO but cant be sure - if you use the windows options you cannot tell which is which from the lists - see my previous posts

i do have YUMI running with loads of stuff on and all versions of windows but like i say when i tried either vista or 7 (cant remember which one) it threw an error during setup

i have VMware installed so may try it later

I figured out how to do it, with the help of this program
43 - Install Windows 8, Server 2012, Win 7, 2K8 & Vista from multiple ISO files on the same Flash drive - RMPrepUSB
So this is an independent program, but I just modified my YUMI install to work with it.
First you need to have Yumi installed on your USB device. All you need to do is try to add a unlisted bootable iso grub. This will create the menu.lst file and other grub setting we can use in conjunction with the linked program above. If you have already done this once then you can skip this step. When this is done download and extract firawiniso to your usb drive. Once this is done you can edit the menu.lst file under your YUMI installation USBDRIVE:\multiboot\menu\menu.lst This file contains the code for the menu where we select our iso files. Add this code to that file for each windows ISO file you want to add. The only thing you need to replace is the title and set MYISO
In this example code the title is "Windows 7 Service Pack 1 64-bit (USB3)" and it will open the ISO Win7ENTSP1USB3x64.iso. You will need to change these based on your setup.

Code:

title Windows 7 Service Pack 1 64-bit (USB3)
debug off
set MYISO=Win7ENTSP1USB3x64.iso

find --set-root /AutoUnattend.xml

dd if=(bd)/firadisk/au.xml of=()/AutoUnattend.xml
dd if=(bd)/firadisk/spaces.txt of=()/firadisk/ISONAME.CMD

root (bd)

write (bd)/firadisk/ISONAME.CMD SET MYISO=\\iso\\%MYISO%\r\n
map --mem (md)0x800+4 (99)
echo Mapping /ISO/%MYISO% as an optical drive...
map /ISO/%MYISO% (0xff)
map (hd0) (hd1)
map (hd1) (hd0)
map --hook
write (99) [FiraDisk]\nStartOptions=cdrom,vmem=find:/ISO/%MYISO%;\n\0
chainloader (0xff)/BOOTMGR || chainloader (0xff)

Any Windows ISO files you want to boot will need to be copied to the ISO folder on the Root of the memory stick. This is the location set MYISO will look for the iso files.

And that is it, you should be able to boot windows ISOs now. This code runs scripts before the windows install starts that mounts the iso as a CDrom drive.

Hope this helps.
