• You only need the ISO file of the XP install CD (which you can make if you have the CD and do not have an ISO file) • You do not need to modify the XP ISO file in any way (F6 can be used to add Intel mass storage drivers manually) • You can only install XP onto a system that has 1GB or more of RAM as the ISO file is loaded into RAM • You can install a vanilla XP CD ISO onto any system - even if it has an AHCI-mode hard disk drive by using F6 to add drivers. • This method does not produce a fully automated install - you will need to press a few keys (similar to running setup from the XP CD) • It takes a total of approx 20 minutes from first boot from your USB flash drive to get to the fully installed Windows XP Desktop. • If you have a non-Intel or new AHCI or RAID controller, you may need to modify the WinVBlock/FiraDisk floppy disk image (instructions provided at the end) • If you do have an IDE compatible system (not AHCI SATA hard disk) then do not press F6 during Setup. Note: Use the 'List Mass Storage PCI IDs' entry in the grub4dos menu to list PCI IDs of mass storage drivers and then refer to the current txtsetup.oem file at the end of this page which has all PCI IDs currently supported to find which SATA AHCI driver you need to select. (This screenshot is a bad example as it does not actually list any SATA devices so no extra SATA AHCI driver would be required in this case!

If a SATA device is listed you will need to select the correct AHCI driver) • Select STEP 1 and hit ENTER. • Hit ENTER to go past the few prompts. You should see a message similar to ' Press any key to boot from CD' - press ENTER again quickly.

If the ISO starts to load slowly into RAM (as in STEP 2 - 2 below) then you need to download WinContig and select your ISO file on the USB disk and defrag it to make it contiguous. Normally, if the ISO file is contiguous this step is instantaneous. • If you have an system that has a BIOS which uses AHCI mode for the SATA hard disk (many BIOS Setup menus allow you to set IDE or Compatible mode for the Hard Disk and this may avoid any problems with the dreaded 0x0000007B Blue Screen of Death if you can do this first!), you will need to load an AHCI driver by pressing F6. If you do not do this you may get a Blue Screen of Death shortly afterwards with an 0x0000007B error or possibly the SATA hard disk will simply not be listed later on. If your BIOS has IDE disks, or has SATA disks but the BIOS is set to IDE mode, you do not need to press F6. However, if you have an Atom based system (Netbook/EeePC, etc.) with AHCI mode set in the BIOS (for instance), here is what you need to do: 5.1. Quickly press F6 when you see the prompt at the bottom of the blue screen.

A new USB multiboot solution. Just copy files to the USB drive and boot. Supports.ISO,.IMG,.IMA,.VHD,.WIM and many more. Prepare USB using Linux or Windows. UEFI-secure boot. Windows Menu editor. Easy to update. Linux ISOs + persistence. Videos + Tutorials.

You will only have a few seconds to do this. 5.2 After pressing F6, it may prompt you to press F2 - ignore this, you only need to press F6 when prompted. 5.3 A short while later you will be prompted to press 'S=Specify Additional Device' to select a driver. Good Traffic Freeware For Fs2004 Update. Press 'S' and select the WinVBlock Bus (32-bit) (should be the preselected in the list) OR the FiraDisk driver and hit ENTER to install it.

WinVBlock does not work on some chipsets (e.g. DQ67 - fails in Setup GUI stage 2 during 'copy files') but works OK on Atom N455 netbooks, FiraDisk works on most if not all systems, so if in doubt choose FiraDisk driver. ALWAYS select the FiraDisk Driver (or the WinVBlock Bus 32-bit driver if you want to experiment).

Use the UP/DOWN cursor keys to select another driver (the list will scroll down to show more drivers). 5.5 You should now see that the two drivers are listed under 'Setup will load support for the following mass storage device(s):' list, one should be the WinVBlock driver FiraDisk driver and the other should be the AHCI driver you just selected. Press Enter to Continue.

You should see a ' Setup is Starting Windows' message. A BSOD at this point indicates you forgot to include the WinVBlock/FiraDisk driver! 5.6 At the 'Welcome to Setup' screen press ENTER to set up Windows XP and then press F8 to agree to the EULA.

Hp Pavillion Dv6 Recovery Disk Download there. Press ESC as you don't want to repair the current installation. Select the partition you want to install XP to in the usual way.

IMPORTANT NOTE: If you did not select exactly the correct AHCI driver entry, then you will only see your USB drive listed by Windows Setup! If this happens you will have to reboot and choose STEP 1 again and press F6 and select a different AHCI driver (or use the Find PCIID menu to find out which SATA controller you have and then refer to the listing at the bottom of the page to find out it's name in the list). You can delete and reformat the hard disk partitions here if you wish (make sure you don't format your USB drive by mistake though!). The copy files textmode phase should now begin. • If you don't see the menu, boot from the USB drive again. • Now choose the 2nd menu item ' STEP 2 - Install XP from ISO on USB (phase 2)'. you should see the ISO file load into memory and the memory counter incrementing - - until the whole iso file is loaded (682Mb in this case). If you do not have enough memory in your system, the iso will be mapped directly and the XP GUI may or may not crash! If it does crash because you have less than 1MB of RAM in your system, reboot to the USB drive again and try the LOW RAM option (which may work).

• When the ISO file has again loaded into memory, press ENTER as instructed and then remove the USB drive (unplug it) - it is no longer needed if the ISO file was loaded into memory. If in doubt (if you saw no memory counter), leave it the USB drive connected - if the Windows GUI mode has a problem later, reboot and try the STEP 2 LOW RAM menu item instead. • The XP GUI install should now proceed just like a normal XP setup. If you are prompted to accept the unsigned Virtual floppy driver ('not passed Logo testing'), just click on OK. Download the correct F6 AHCI/RAID disk image/files for your system. This is normally a 1.44MB floppy disk image, or a group of files comprising txtsetup.oem and at least one.sys,.inf and.cat file. The system manufacturer normally provides these files.

For instance, if you have an Asus EeePC, go to and select you model of EeePC, then choose XP as the OS and download the AHCI driver from the SATA drivers section. This is just an example as Atom AHCI drivers are already included in the WinVBlock.ima.gz disk image.

Place them in a new empty AHCI folder on your hard drive. IaAHCI_DesktopWorkstationServer] id = 'PCI VEN_ 8086 &DEV_ 1C02&CC_0106','iaStor' Now look for the section that lists iaAHCI_DesktopWorkstationServer in the [SCSI] section - it lists: iaAHCI_DesktopWorkstationServer = ' Intel(R) Desktop/Workstation/Server Express Chipset SATA AHCI Controller ' So Intel(R) Desktop/Workstation/Server Express Chipset SATA AHCI Controller is the correct driver to select for PCI ID 8086 1C02. Note: 8086 is the vendor ID for Intel.

If you have an 8086 Vendor ID then the driver will probably be in the txtsetup.oem list - if it is not an Intel SATA PCI ID you may need to modify the txtsetup.oem file and add more drivers.
