Hi!

I want to install as secondary OS 64-bit Windows XP.
I have disks partitioned and want to place Windows XP partition on other physical disk than 10.
But I don't want to overwrite master boot record (MBR).
So, Q is simple: How to eliminate master boot record overwritting?
Is enough to disable disk in BIOS or requires physically disconnect it?
Problem is that I'm using 5 SATA HDDs.

Thank you for each help.

Two simple options, not ruling out additional options...

1) Run XP in a VM.
2) Install XP on separate physical drive, use BIOS/UEFI boot drive selection menu to boot from XP drive.

I need to use XP for special hardware supported only for XP/2003. I'm using 64-bit Windows 10 - for this XP64.
VM works not with real hardware, no matter VBox or VMWare.
Ok, I'll install simply on other drive, I was not sure if it overwrites MBR.

Hi!

Look at screenshot - my Windows 10 has MBR, look at.
So, what I have to do and what to do not?

Please standby. Take no action based on what you read below. DO NOTHING

@jmarket This is why I need Advisor status. Please ping someone who will review the following:
On Disk0 (shown as Disk1), shrink Part1 or Part2; create 4th Primary?
 
I want to do this:
Disk 4 (Disk 3) - Part 4 (Part 3) = APPS > move files away and install XP there.
Is it ok?
Miro
 
You know that to install another OS, the partition must be erased right?

Windows XP does not support GPT. The 64-bit version of XP supports GPT but only for data volumes, not for boot volumes. That means that in order to install Windows XP, you must erase the entire drive and format it as MBR.

What you're trying to do can not be done without wiping the drive and formatting it to use a MBR.
 
I own software for GPT drive to MBR conversion... can it damage data? Really never tested. I know that it can recover partitions and many others, so tool I have, but Q is really important.

Why? edit: never mind.

@jmarket
Looks like WindX is installed on the (sloppy) MBR Drive1.
Shrink some space.
Create 4th Primary partition
Install XP
Boot from WindX install media, Repair option (or other suitable tool, Macrium?) which would repair the MBR
Add entry in BCD for XP.

Result=
Dual boot WindX and XP from Disk1 MBR

You would be wise to NOT implement my suggestion without confirmation from another tech.

I am not very smart.
 
Out of interest what is the hardware you mention? "XP for special hardware supported only for XP/2003"
 
Hardware is not only for XP and 2003 - it's up to XP/2003 - later not supported.
It's Catweasel MK4 - floppy disk simulator for retrocomputing.
Miro
 
Really not!
It is always Q from people interested in not. Please don't mean that I think about you anything wrong! For you it is correct Q.
USB floppy has not true interface and controller - it is impossible to read/write disks for example Commodore GCR (even GCR reads not real drive).
Catweasel allows to connect 3,5" and 5,25" floppies and reads/writes all Commodore formats - Commodore 8-bit computers are my hobby.
In my eyes I don't understand end of support while is Catweasel distributed. Last drivers are for XP/2003...

easy solution, spend the $50 on a cheap XP box you can probably buy 5 for $50 :ROFLMAO: problem solved!!
