Installing Windows 7 From USB Drive 3 Steps Easy Process

actually there is no need to use ultraiso or anything else. I made my usb a bootable one, and I directly extract the iso image to the usb and that's it.It only takes 14 minutes to install win7 from usb.

 

thanks for this fast tutorial
works perfect

 

First time installing OS from usb and I was amazed at how fast it installed. I will never install an OS from a dvd drive again. BTW, for those that need a program to make a boot usb try "A bootable USB".

 

i am just posting to confirm that u can do this stuff also with a 4GB microSD card and a card reader, both with x86 and x64 versiosn of win 7

 

I already posted the complete command for to create a "clean" bootable USB stick and here again some command is missing.

But I'll write it again:

Open the command prompt by hitting: WIN-Key + R and type CMD [enter]

type:

diskpart
list disk (this will show all list in the computer and you need to use the disk # from the USB Stick you like to use)
select disk #
clean (this will totally erase the USB Stick and delete all partitions)
create partition primary
select partition 1
format FS=NTFS (best is to use NTFS for any Windows Boot Device)
assign (this will automatically assign the next available drive letter)
active (which is activating the formatted USB Stick)
exit

If you haven't done yet, mount the ISO Image or use the Windows DVD in the drive and use the following command from the BOOT Directory of the mounted image:

bootsect /NT60 #(Drive Letter of the USB): [enter]

After finish, close the Command Windows and copy ALL files from the ISO Image or the DVD to the USB Stick.

Now you have a CLEAN and new formatted bootable USB Stick with Windows 7 files for to install.

oh, it was posed on the previous page, silly me

 

Does this work for Windows XP as well?

 

Has anyone tried to put XP/Vista/7 and a handful of Linux on a huge USB drive? I'd imagine it would be pretty involving process considering how long it took me to get a all in one DVD from scratch.

I tried this on a Windows 7 7600.16385 Ultimate x86 ISO
Worked like a charm
Thanks...Though Im yet unwilling to uninstall Windows 7 RC1 7100...Will wait till October 22 and then have a relook at the existing lo*d**s n cr*c*s

 

This is painful... I don't like UltraISO. I waited for 2hrs for it to 'burn' the iso to my usb key and it was only 50% done. I cancelled it, formatted drive, extracted iso and copied files over, took 10min.

edit: OK so obviously this didn't work lol. Boots me into DOS. Either way, ultraiso takes forever for some reason, I can't figure out how to make it quickformat before it writes instead of regular slow format.

I read the 'difficult' windows instructions that basically just tell you to format it and copy files over. Not sure why ultraiso is needed. Now, lets see if this works, else I'll need to wait 4 hours for ultraiso to slow format my usb key. *fingers crossed*

 

Worked just fine here. Make sure you are using the latest edition of UltraISO.

 

Take a look at the commands below how to manually create the bootable USB
Stick for Windows 7:

Here the steps:

1.Press Win Key + R (to open the Run command)
2.type: cmd [enter]
3.type: diskpart [enter]
4.type: list disk [enter]
5.type: select disk # (number of the USB Stick) [enter]
6.type: clean (for to delete the existing partitions and clean the stick) [enter]
7.type: create partition primary [enter]
8.type: select partition 1 [enter]
9.type: active [enter]
10.type: format FS=NTFS QUICK [enter]
11.type: assign or assign letter=X (X the drive letter you like to have) [enter]
12.type: exit

Next have the DVD or the ISO file (mounted) ready and type in the command window:

F: (if the dvd is in drive F) [enter]
cd\boot [enter]
bootsect /nt60 X: (x the drive letter of the USB Stick) ][enter]

or

C: (if the mounted ISO is in drive C:, or use that driver letter which holds the ISO)
cd\[DIR]\boot [enter]
bootsect /nt60 X: (x the drive letter of the USB Stick) ][enter]

**The bootsect command will transfer the needed bootfiles to the USB Stick

After that copy the whole contents of the DVD or the ISO to the USB stick just by using the Windows Explorer.

You're done and now have a clean bootable Windows installation media.

 

UltraISO method worked perfect, unetbootin not!
Thanks for the info.

Why is it that whenever it restarts under installation it goes back to the start of the installation and not continue from where it ended?
