Windows is my favourite OS since the Windows 7 edition. Usually we install most of OS from CD/DVD ROM. What about an USB or an SSD? You can do install Windows 7/8 from a boot able USB/Pen drive, but simply copying all CD contents to USB doesn’t work at all.
There are many programs which can reincarnate USB into bootable USB. But I suggest do it like an expert with some simple command.
Connect your device to a Windows installed system/PC also connect the USB want to use with a primary slot. We need at least 8 GB for installation purpose.
We are going to format the USB, make sure all the necessary data is backup from the storage device.
Preparing the USB with command prompt
Launch the command prompt with Admin privileges( Run -cmd and press enter) and type c:/windows/system32 and issue the DISKPART command. Now you have two command window.
Now list all disk partition with DISK LIST and identify your partition number, go to my computer and check volume size if had a confusion. The size will be 7534 MB for the 8 GB USB and I have disk with no 1.
Select the partition by issuing select disk [Disk #] command here it is SELECT DISK 1 for my computer, it may vary depending on the hard disks of PC you are using.
Now clean the disk. Issue CLEAN command and make a new partition using CREATE PARTITION PRIMARY and make new partition active with ACTIVE command
Need to format the newly created partition with the format command. FORMAT FS=NTFS QUICK. It will take some time to finish the process. Have a tea …. lol
Now we need two commands which let you go to the finalize step , ACTIVE and EXIT command (you will be automatically exit from the diskpart utility), don’t exit the command prompt.
Go to your My computer and load the Windows installation DVD and not the drive letter of DVD and US , suppose I have letter ‘E’ for DVD and F for USB.
Now the command prompt look like C:/Windows/System32>, OK ? lets make the bootable records follow these steps (issue following commands)
- E: CD BOOT and repeat CD BOOT until the prompt changed to E:/BOOT> (‘E’ stands for DVD Drive)
- Lets update USB Drive ‘F’ with BOOTMGR with compatible Bootcode, issue the BOOTSECT.EXE/NT60 F:(USB Drive).
If everything goes right( You will get the message ‘Bootcode was successfully updated on all targeted volumes’) , it will be OK for copying complete Windows (7/8/8.1)DVD content to the USB.
How to Boot
Choose your BIOS feature to make your USB device booting device, the setting may vary depending on the different BIOS. Now you know how to install Windows for USB.
Connect the USB to a computer and restart , boot with USB…
