Hab grad einen sehr simplen Guide dazu gefunden, und will ihn gerne mit Euch teilen. Für mich ist das eine sehr praktische Lösung, vor allem, wenn man mit unattended setup und zusätzlich zu installierenden programmen rumspielt.
Hier der Guide:
It surprised me to find that there are very few dead-simple guides to
creating a bootable USB thumb/pen/flash drive for a Vista and/or
Windows 7 installation. I cobbled together the following from VistaPCGuy and another source I don’t remember right now.
This will walk through the steps to create a bootable USB flash drive
for the purpose of installing a Vista or Windows 7 OS. These
instructions assume that you have a computer with Windows Vista
installed on it.
Required:
USB Flash Drive (4GB+)
Microsoft OS Disk (Vista / Windows 7)
A computer running Vista / Windows 7
Step 1: Format the Drive
The steps here are to use the command line to format the disk properly using the diskpart utility. [Be warned: this will erase everything on your drive. Be careful.]
Plug in your USB Flash Drive
Open a command prompt as administrator (Right click on Start >
All Programs > Accessories > Command Prompt and select “Run as
administrator”
Find the drive number of your USB Drive by typing the following into the Command Prompt window:
diskpart
list disk
The number of your USB drive will listed. You’ll need this for the next step. I’ll assume that the USB flash drive is disk 1.
Format the drive by typing the next instructions into the same
window. Replace the number “1” with the number of your disk below.
select disk 1
clean
create partition primary
select partition 1
active
format fs=NTFS
assign
exit
When that is done you’ll have a formatted USB flash drive ready to be made bootable.
Step 2: Make the Drive Bootable
Next we’ll use the bootsect utility that comes on the
Vista or Windows 7 disk to make the flash drive bootable. In the same
command window that you were using in Step 1:
Insert your Windows Vista / 7 DVD into your drive.
Change directory to the DVD’s boot directory where bootsect lives:
d:
cd d:\boot
Use bootsect to set the USB as a bootable NTFS drive
prepared for a Vista/7 image. I’m assuming that your USB flash drive has
been labeled disk G:\ by the computer:
bootsect /nt60 g:
You can now close the command prompt window, we’re done here.
Step 3: Copy the installation DVD to the USB drive
The easiest way is to use Windows explorer to copy all of the
files on your DVD on to the formatted flash drive. After you’ve copied
all of the files the disk you are ready to go.
Step 4: Set your BIOS to boot from USB
This is where you’re on your own since every computer is
different. Most BIOS’s allow you to hit a key at boot and select a boot
option.
I used these instructions to get my new Dell Mini 9 laptop loaded with Windows 7 (the PDC bits). HTH.
