Are you a person recently purchased a netbook which is not having a DVD ROM, No problem, you can install any OS using a pendrive or USB’s.
Here is the steps.
1. A 8GB pen drive (since the size of Windows 10 is 3.2GB)
2. Windows 10 installation files or a iso image of Windows 10 OS
3. Administrative privileges in the OS
Step 1 : Take the backup of all the data in your usb drive plug into the Machine.
Step 2: Go to device manager (Control panel –> device manager –> select disk –> select your usb drive ) and then right click –> properties –> go to policies –> Select Better performance). This step is needed for faster installation of windows 10 (You can wonder, windows 10 installed within 15 minutes with just 1GB RAM) See the following video
Step 3: open the command prompt with administrative rights (Accessories –> right click Command prompt – and select run as administrator)
Step 4: type DISKPART (you will get a prompt as DISKPART)
Step 5: type LIST DISK (it will list all the disks), please remember the disk number of your pen drive (see the following picture)
So, mine is disk 1
Step 6: Execute the following commands one by one,
SELECT DISK 1
CREATE PARTITION PRIMARY
SELECT PARTITION 1
FORMAT FS=NTFS (since windows 7 permits only NTFS, the USBs also to be formatted as NTFS, and this process will take some time)
Step 7: Now insert the windows 10 DVD drive or if you have iso image, using winrar extract it to a folder
Step 8: go to the concerned folder in the command prompt (assume installation files of windows 10 as E:/win10)
execute the command in command prompt
BOOTSECT.EXE /NT60 G: (assigning the bootmanager to the USB. G is the drive letter for my USB)
Step 9: After getting the successful message, copy the contents of your Windows 10 installation files to your USB Drive. Thats it.
Enable Booting from USB option in your BIOS and lets see the installation will complete within 15 minutes.!!!!
