Try this to install windows 7 from usb drive

Step 1 – Let’s create a bootable USD Drive!

• Clearly, the first thing you need is a USB drive and the one I used was an 8GB Seagate model.
• Plug the drive into your PC.
• Open a command prompt as administrator.
• Get the drive number by typing:
• diskpart
• list disk
• On my machine the USB disk was number 1.
• Format the drive by typing:
• select disk 1
• clean
• create partition primary
• select partition 1
• active
• format fs=NTFS
• assign
• exit
• Mount the Windows 7 beta iso using Daemon Tools or similar.
• Navigate to the boot directory
• cd E:\boot
• Using bootsect, we’ll make the USB drive a bootable NTFS drive, ready for a Windows 7 image (my drive was labeled G):
• bootsect /nt60 G:
• We are finished with the command prompt now, so you can close it.

Step 2 – Copy the installation files from the mounted Windows 7 iso to the USB drive.

Step 3 – Install on the computer

• Plug in the USB drive and turn on computer
• On start up press <F12> to select the bootable drive
• Select the USB drive and press return
• The computer will boot from the USB drive and the installation will begin
• Install as normal.

hi,
when you use XP's diskpart utility it wont install windows 7. You'll have to use Vista's diskpart utility. Vista uses bootmgr, the same as Windows 7.The reason is in the way they create the MBR. windows XP puts ntldr in the MBR and hence, when you start up, it's say missing ntldr.

Get a 4GB USB Drive and plug it in under Vista (i don’t think XP has diskpart)

-Click Start –> type CMD and right click Run as Admin
Inside cmd, type and enter the followings:

• diskpart
• select disk 1 (your primary hard drive is denoted disk 0)
• clean
• create partition primary
• select partition 1
• active
• format fs=fat32
• assign

exit

- Open your drive under explorer, copy all files from vista/7 iso to the usb drive.

- in Bios, set to boot from USB and have fun.

hi,
Windows 7 is about 2.5GBs so make sure you have a 4GB flash drive before you think about starting this process.

For installing windows 7 from your hard disk you have to replace window XP boot loader with window 7 boot loader. Window 7 bootloader loads the window 7 setup files. Follow these simple steps for doing this
Step1: Open the downloaded file
Step2: Extract the following files and folder to C drive or the system drive which has primary partition.
Boot, Sources, bootmgr
Step3: Now go to start > Run> cmd> and type the following thing
cd c:\boot bootsect /nt60 SYS
Step4: After this start your system and window 7 installation will start.
(Make one thing for sure do not install window7 on your primary partition or C

Hello guys,

Can I use the methods explained up here to create an instance of W7 on my external HDD? Some say it is impossible (Installing Windows 7 on external Hard drive?) and others say it is possible. So basically what I want to do is making a partition of my external HDD bootable and boot W7 from there. Another thing: I'm not shure whether or not the BIOS (AMI) of my computer supports booting from USB, I couldn't find a thing like mentioned in earlier answers.
