Installing Windows From USB

KB ID 0000191

Problem

This weekend I needed to install Windows 7 on my shiny new Acer HTPC, but having no internal CD/DVD drive I needed to do this via USB.

Quite a few times now I’ve needed to install Windows (Particularly Server 2008), on a machine that has no DVD Drive. You can now install both products from a bootable USB drive by doing either of the the following.

Note: You will need a USB Drive with enough free space on it to hold the Windows setup files (Windows 7 and Server 2008 require 4GB ish, depending on versions).

Solution

Option 1 (The quick and dirty techie way!)

1. Pop in your USB Drive > open a command windows and execute the following commands:

[box]diskpart {enter} [launches the disk partition program]
list {enter}[Displays all the disks you can work with]
select disk x {enter}[Select the USB Drive number]
clean {enter}[Wipes the USB Drive][/box]

2. Execute the following commands:

[box]create partition primary {enter} [Creates a new primary partition]
select partition 1{enter}[Select the partition you have just made]
active {enter}[Makes the partition bootable]
exit {enter}[Closes diskpart][/box]

3. Now use a utility like 7-Zip to extract the Windows Install media .ISO file to your USB drive.

4. Now boot your device from USB, (Enter the BIOS boot section and change the boot order), or press the key the machine says will load the boot options when you first turn it on.

Note: Some machines require you to change USB emulation before you can boot from them like so.

Option 2 (The lazy way!)

Dell PowerEdge – PERC RAID Card Importing / Using ‘Foreign’ Disks

KB ID 0000639 

Problem

I bought some SAS disks from eBay to go in my Power Edge 2900 Server, and scratched my head for a while trying to get the PERC RAID controller to use them. I could only see them marked as ‘Foreign’. Probably because they did not have their original config ‘wiped’ off them before I bought them.

Solution

1. Boot the server, Press CTRL+R when prompted, then press ‘C’ to enter the Configuration Utility.

WARNING: DONT clear the config on the controller or you lose ALL your Virtual Disks / Arrays.

2. Select the controller > F2 > Foreign Config > Clear > Confirm.

3. You can now add the disk(s) as a new Virtual Disk.

4. I’m just presenting one 300GB SAS disk as RAID0 here.
