Installing Windows 7 on Asus Eee PC Netbook 900 using Pendrive

I have been using Asus Eee PC Netbook 900 since couple of months now. It came preinstalled with Microsoft Windows XP Home. It has 2 SSDs, 4GB and 8GB with 1GB RAM.I used it for few days as it came , then decided to install Windows 7. XP Home was installed on 4GB SSD and some apps were installed on 8GB SSD. So installing Windows 7 was bit tricky as the Netbook does not comes with any Optical drive. Either I have to get an external DVD drive and connect to USB port and install it as usual or to use a Pendrive (FlashDrive). I decided to try with Pendrive. Here are the steps required for doing so. Actually I started this post soon after I installed Windows 7 about a month back, but completing and posting it now.

Get a pendrive with minimum of 4GB capacity. I am using a 4GB Kingston Pendrive.


To make the pendrive bootable, follow these steps which is to be carried from either Windows Vista or Windows 7.

Attach your Pendrive to USB port of your Windows Vista or Windows 7 machine.

Click on Start and type cmd in the Search window, which will show the cmd as the result. Right click on cmd and Run as Administrator, which will open a cmd window.  Now at the command prompt type Diskpart and press enter to get a Diskpart prompt where we will enter further commands.


Now at the Diskpart prompt , DISKPART> type these commands- (commands shown in Bold and Italics)

List Disk -which will list the disks including your Pendrive, as can be seen here its listed as Disk 1 with 3820 MB size.

Select Disk 1  -(here its 1 for me, replace 1 with the number which is shown against your pendrive) , which will show ‘Disk 1 is now the Selected disk’.

Clean   –This will clean the pendrive disk

Create partition primary


format fs=fat32 quick

assign  –A drive letter will be assigned to the Pendrive. And its Bootable.


If you get any error along the way, just remove the drive and repeat the process from start.

For those who are uncomfortable with issuing these commands, can try an utility which automates this process. A Bootable USB utility to create bootable USB drives for Win 7 and Server 2008

Note that this also requires to be run on Windows 7 or Vista, Server 2008. I haven’t tried this utility.

Insert your Windows 7 Install DVD and copy all the contents from it to the pendrive .This can be done from Within Windows. So just do a copy –and paste into PenDrive . Now you have a Bootable Windows 7 pendrive which will be used to install on your Netbook.

I have followed the above steps from the Installing Win7 using a USB Stick by Dennis Chung. And these steps are General.

Let us start the installation process on Asus Eee PC 900 Netbook-

And from now on I’ll be talking of Asus Eee PC 900 Netbook , so some of the screenshots may not be applicable to other Netbooks. Insert Bootable Windows 7 USB Pendrive into your Netbook USB port.


Start your Netbook and as you see Asus Logo Screen,


Press F2 to enter into BIOS and set the Boot Sequence Priority to ‘Removable Device’.


Also OS Installation option to ‘Start’


And Now Save and Exit. And Netbook restarts and see if it boots from your Pendrive. If it does then continue installing . Else restart and when you see the Asus Logo Screen press ‘Esc’ key to go to the Boot Device Selection Screen-



As you can see in the above pic, I have selected USB:Kingston DataTraveler which is the pendrive I’m using. Press Enter and continue booting from the USB Pendrive and now it starts Windows 7 installation process. Follow the screen Instructions you get.



As your Asus Eee PC900 comes preinstalled with XP on 4GBSSD and various Apps on 8GB SSD, now you have to install Windows 7 on 8GB SSD thus wiping out all apps. First I installed Windows 7 on 8GB SSD, dual booting with XP. I used dual booting for few days keeping both Windows XP and Windows 7, later I removed XP from 4GB SSD also.

It took me about an hour to install it with all drivers searching etc on the Eee PC900 Netbook. It installs almost all drivers, you can install others from the DVD provided with the Eee  PC 900. You have to copy the contents from the DVD to Pendrive to do it. Actually some people using External Hard drives using USB port to connect with Windows 7 set up on these Hard drives could install Windows 7 within 15 min. on regular laptops.

You may have to get newer ACPI drivers from Asus support site to install thus making all the Fn keys on Windows 7 Netbook working. Get the Version V4.00.0010 ACPI drivers from Asus Support site, its under ATK category selecting OS as XP.

After the installation, restart and go into BIOS and set OS installation option in BIOS to ‘Finished’ which we had set to ‘Start’ for the OS installation. Don’t forget to do this else you may face some error or performance issue.


On a 8GB SSD , after the install nearly 1.2 GB was free out of 8GB.Also note that i have not vLited it. Its a normal install. As I do not need Hibernate option, I switched off Hibernation which further freed me nearly a GB. Issue the command from cmd prompt as ‘powercfg –h Off’  (without quotes)  to switch off Hibernate. Thus I have nearly 2GB of free Space on 8GB SSD where the OS is installed and as I removed XP I have nearly 4GB on another SSD. Here I’ll install all other Apps.



As it also provides a SD/MMC slot, I have put a 16GB SDHC card, thus providing ample storage space. *And I am also using this for Boosting the Windows 7 performance with its ‘ReadyBoost’ feature. Its not a new feature and users of Windows Vista must be familiar with it. I have allotted nearly 4GB to ReadyBoost and rest for storage. So instead of using Pendrives, one can use SDHC cards for ReadyBoost which will sit inside of slot and will not stuck out when Pendrivs are used.


I am running various apps and software including MS Office 2010 TP and it runs quite fast on it.

Windows 7 RC runs quite smoothly on such a lower end system (Its Intel mobile 353 processor with 1GB RAM). So if you have a Netbook , give it a try, you’ll like it. When Windows 7 comes into market , I’m sure there will be many Netbooks coming out pre-installed with Windows 7.

EDIT: 26/09/10 Editing, after some of my readers pointed this out. * On my SSDNetbook, ReadyBoost installed like any oth HD based sys, though ReadyBoost are supposed to be disabled on Windows 7 running on SSD & it may even decrease performance on SSD. SSDs available presently are blazing fast as technology improves, may be some SSDs available at earlier stage might be slow.

Thanks for pointing that out, actually I had forgotten to edit that thing.

    Phew. You just went and did it the hard way;-) Looks a little tricky, Vasudev, and I wonder how \’7\’ will really perform on these netbooks, now I\’ve read this post. I\’ll have to save this for future reference. Well done, brave soul!

  2. technogran says:

    Brilliant post Vasudev! I would probably put Windows 7 on my external USB drive and then transfer it to the Netbook. Just goes to show that Windows 7 will run on just about anything! A very useful post.

  3. Vasudev says:

    Hi Jen ,preparing your pendrive and making it bootable is also very easy. Once you do that installation is just normal. Follow the On-screen installation. Mine is a bit older Netbook. Newer Netbooks comes with Atom Processor and also comes with regular HD as 160GB etc. So space is no constraint. So with bigger HDs you can just copy the Windows 7 DVD contents on Pendrive, transfer it to your netbook and run installtion from there. Making a pendrive bootable is not needed. Else get an External USB DVD Drive , connect it to Netbook and boot from there and install , Just like any other Install. Mine is a 4Gb+8GB SSD based, so you can see I had to adjust for Spaces. Speedwise SSDs are faster and Windows 7 runs smoothly on my Netbook. In future you may see larger capacity SSDs becoming a norm replacing the regular HD. Yes, you will not get Aero effects etc. on a Netbook like mine.You can keep looking for ads for Windows 7 Netbooks as Windows 7 Release dates nears. (Oct 22) . MSDN /TechNet Subscribers will get it tomorrow (Aug. 6th )

  4. Vasudev says:

    Thanks Technogran ! Yes If you have a bigger HD based Netbook you can do it. Else using an external DVD drive will also be an option. Yes Windows 7 runs smoothly on older hardware also. I have been running it on an Old desktop , AMD 1.7GHZ with 512MB RAM out of which 32MB shared by video . And it runs smoothly.

  5. Buysox says:

    To minimise writes to the SSD, consider moving the swap file and any other temporary files such as IE temp files to the SD Card.

  6. Jen says:

    Thanks for your comeback, Vasudev. If the "normal" HDD is available – then, I an opt for that. Shame, as I really fancy the SSD drives, but someone confirm or deny: Are Flash drives only good for around 1,000 hits? That can\’t be right, or we\’d all be replacing the bloomin\’ things at a rate of knots! Forget who mentioned that (some time ago) but I wasn\’t pleased to hear it!

  7. Matty says:

    great post Vasudev, very easy to understand :)two questions though, presume this will be all exactly the same for windows xp? should be able to get my hands on a disk for that more easily. and also, if i cant get a disk, will it be ok to use a downloaded version, will i still have everything i need to work it this way?

  8. Vasudev says:

    Thanks Matty. Yes you can use the method for Windows XP also. For downloaded version you can try connecting External Hard disk and then try installing it from there on your Netbook/laptop. (Sorry for the delay in reply)

  9. Vasudev says:

    Yes Jen, you can opt for normal HDD also. Its available in larger capacity (160GB) compared to SSDs, at present . No, its not correct that Flash drives are good for 1000 hits. That\’s wrong. Everything has MTBF but here it should be quite high and not just 1000.

  10. Jen says:

    Phew, Vasudev! Glad to see the 1000 hits thing is wrong. Actually, I\’d forgotten about this page as it\’s some time since I read it. Just come home and saw my name mentioned. Piled in to see who the guilty person was who named me;-) Hmmm – well, if the SSD\’s get a bit beefier, it might be better to go for that. I\’ll see, over the next few months. Ta for reply.
