A short troubleshooting roadmap and practical steps that fill gaps left in the thread (references: , , , ).

First, confirm what the installer actually sees. In Vista open Computer → Manage → Disk Management, right‑click the disk number → Properties → Volumes and note the Partition style (MBR or GUID). Also verify the drive appears in the firmware/BIOS and which SATA/IDE mode is selected. If the disk is GUID (GPT) or a dynamic volume, the stock XP installer will refuse to install; that fact points toward conversion or a different install approach rather than a simple partition resize.

GParted workflow (practical, low‑risk order): in Vista run full defragmentation and chkdsk /f, temporarily disable the pagefile and System Restore, then create a GParted Live CD/USB from the ISO and boot it. In GParted use “Check” on the NTFS partition, then “Resize/Move” to create unallocated space, apply and wait without interruption. Reboot to Vista, re-enable pagefile/System Restore and run chkdsk again. A verified backup or image of the recovery and system partitions should exist before any resize.

If XP setup still reports “no disk”, two common paths exist. A temporary switch of the BIOS storage mode to IDE/Compatibility can let the out‑of‑the‑box XP installer see the drive — but changing the mode can prevent Vista from booting unless its controller driver is present. The safer long‑term option is to inject the laptop’s mass‑storage drivers into an XP installation image (tools such as nLite or vendor driver packs) or use the legacy F6 driver method if the hardware supports it. If the disk is GPT, conversion to MBR is required for a BIOS/XP install and that conversion will erase the disk.

After XP is installed the Vista boot entries will need repair/rebuilding (as noted). Keep the recovery media that created and make an image backup before proceeding.

please make free the one of yours partition your hdd,than inser the bootable windows xp cd,than you can instal the windows xp os to that free partition

Hi sisi. windows vista handles its boot files and partitions diff from windows xp. so xp wont understand a drive managed by vista.

to make a dual boot system you need special tools that rebuild the vista boot files and add xp boot files to them. google for dual booting vista. youre option is the hardest to deal with as you most likley dont have a vista bootable dvd to boot from. if you did you could backup your drive and wipe it and install xp then vista which is the simple path to take.

your looking for EasyBCD 1.7 or higher, this is a tool that allows you to install xp after vista. any partitions you want are best set up in vista via control panel/system and maintenance\admin tools\computer management

dont put xp and vista in the same partition or they will kick the crap out of each other.

i dont know your pc skills so no i'lls intended, but you must backup your excisting partions on laptop before you start especially the recovery partion.

You say xp cant read the hd, in some cases laptop sata drive interfaces Aren’t recognized by xp so you may have to identify the drivers and build a boot cd with them added.

well thats given you stuff to think about best google for dualbooting vista on youre make of laptop also, some ones prob done it....

Hello ,thanks for you reply to my thread with all this good information .Now i will be able to search for the dualbooting and try to install xp on vista.Therefore , i do have one more question concerning my harddrive.You mention i should make a recorvery cd to make my harddrive reconise by xp .SO i already have the backup cd of my laptop .I already made that cd when i instal vista first . So can you help me out how i can make my hd apprear thx you

the link i posted above gives the directions from beginning to end.

Yes thx for the link. But they mention you need to put vista dvd and boot my latop .I dont have vista Dvd .

CAn you help me to play the gparted file ?

I dont know how to use gparted ? Can any one help me out please . I try everything to make a free space in my drive but its cant be reconigze when i put xp cd inside.

Hi sisi.. ..

The vista backup dvd is for when you want to restore the laptop to prev state should things go wrong. it wont help xp find the hard disk..

if you want to prepare the partition for xp before you begin, Boot to vista and use its disk management tools to free up some space on drive and make a partition.

If you had a vista dvd you could use its disk tools by booting from it.. forget about vista dvds and focus on gparted and the easybcd tools the link prof pc gave you has all the right info if you dig deep enough.

heres another link to download an iso image of gparted which you can burn to cd by using your burning software. the site also has manuals and guides for using gparted.. This might be an easier option 4u or it might not... its something else to try.. info alone might be enough..!!!


1.......prepare a partition on laptop HD
2.......boot to xp and install it to new partion
3.......start xp and install the easybcd tool
4.......use easybcd to repair the vista boot files (which also adds the xp boot info to vista boot files)

If..... after setting up a partition you boot to xp and it cant find the new partition or the laptop HD then xp does not have the drivers on its cd for SATA interface on the laptop.. its a rare scenario but does happen.. if this happens to you then you have to research you're laptops hardware and find xp drivers for it. (make sure xp cd is SP2 aswell before starting!!! prob is..)

problem is you will still need other software tools to build a new xp boot cd that includes the new found drivers.. I hope xp does find your sata drive on laptop because if not it will double the amount of work involved...

good luck..

link for using gparted

download version 3.4-7 as its the same as in the tutorials on apc website...
