Here's info on how to fix it once you've found a way to boot with the same windows version as you have on your laptop:

A disk read error is very common; it usually occurs as soon as your computer boots up from SSD, HDD or another hard drive and has affected a large number of users of Windows 10/8/7/XP.
This error has the message "A disk read error occurred. Press Ctrl+Alt+Del to restart" on the screen like the picture below:
This message indicates that your hard drive has a problem when the operating system attempts to read the disk. That is, the disk is preventing the computer from entering into its operating systems.
Simply put, a disk error could be caused by several reasons such as incorrect boot order, BIOS issue, IDE cables failure, incorrect MBR configuration, faulty hard drive, etc.
When meeting such an issue, no matter how many times you restart your computer by pressing "Ctrl+Alt+Del" keys, this error still exists.
In the presence of this issue, it will still exist regardless of how many times you restart your computer by pressing "Ctrl+Alt+Del". In fact, a disk read error is not a problem that can be solved by a simple restart. But don't worry, this post will tell you top seven useful solutions to a disk read error occurred SSD.
How to Fix Disk Read Error Windows XP/7/8/10

Solution 1: Boot OS from Hard Drive

If a disk error occurred, the first thing to do is to check whether the boot order is correct in BIOS.
There are different ways to get into BIOS in different computer models and operating systems. When turning on the computer, the first boot screen will usually show you what key to press to go into the BIOS.
You can refer to this guidance How to Enter The BIOS On Your Computer. Once you are in BIOS, find the boot order section. In the boot order section, check to make sure the correct hard drive is placed as the first boot priority before any others in the listing.
Changing this setting might be enough to help your computer boot normally. If it is still unbootable, try the next solution to fix disk error occurred.

Solution 2: Reset or Upgrade BIOS

Resetting your computer BIOS to default or upgrading to the latest version might be able to solve "A disk read error occurred" in Windows XP/7/8/10.
Here is the step-by-step guide to reset BIOS:

1. Press a specific key (F2, F8, F12, Esc or Del) according to your computer model and OS to enter into BIOS.
2. Find the option to reset BIOS to default.

Tip: The option name is different depending on different computer manufacturers and BIOS versions, which can be "Load BIOS Defaults", "Load Default Settings", "Load Fail-Safe Defaults", "Load Setup Default" or "Get Default Values". Choose one according to the real case, then save this change.
If the disk read error on boot up persists, try the following solution.

Solution 3: Repair Master Boot Record and Boot Sector

A corrupted or damaged Master Boot Record or boot sector could cause disk errors. Therefore, repairing the MBR or boot sector might be able to fix the issue"A disk read error occurred" with USB boot.
You can use a professional and reliable partition and disk management tool - MiniTool Partition Wizard - to repair your MBR in Windows XP/7/8/10.
As a dedicated partition manager, MiniTool Partition Wizard could be used for many operations such as resize/move/extend/copy/wipe partition, rebuild MBR, migrate OS to SSD/HD, copy disk, recover lost partition, perform data recovery, and so on.
Here we strongly recommend MiniTool Partition Wizard Professional Ultimate Edition. This edition has a feature called "Bootable Media" based on Win-PE; it is designed to manage disks and partitions when the operating system fails to boot or when there is no operating system.

Sounds like a disk issue. It kind find the OS so it's then trying to PXE boot (boot from the network). Have you changed the boot order recently? or do you have a USB key connected to your server? are you able to connect to the management interface (hp ilo, dell drac) to see if you had any raid or other hardware issues?

Set the hard drive to boot first, I find this fixes most boot errors.

An unmountable boot volume error suggests that you may have a hard disk failure or at least some corruption to the hard disk which the system uses to boot Windows XP.
To try to resolve this problem you would need to use a specialist boot CD to try to repair the disk errors. One such disk is Hiren's Boot CD which can be downloaded as a CD image file (.ISO) then would need to be burnt on to a blank CD then the computer booted from this CD.
On the initial Hiren's boot menu, select DOS programs, then select Disk tools before selecting HDAT2 to perform the disk repair actions.
HDAT2 can take some time to complete depending on the size of your internal disk drive and the number of bad sectors or other errors encountered - the tool will attempt to repair bad sectors by reading, verifying, writing and re-reading / verifying the data.
If the disk can be recovered, then you may be lucky and the system will be able to boot but otherwise, you may still need to do some further recovery work for the operating system, in which case you may need a Windows install CD or other recovery CD media.

If HDAT2 finds a lot of unrecoverable errors then you should seriously consider replacing the drive - you should be able to recover data from the old drive using other tools on the Hiren's Boot CD, including booting the CD mini-XP environment and using the tools there too.

This error is caused by the boot device (hard drive, DVD, etc) not having the required Operating System files. You may need to find a different Boot Device, like maybe a DVD, with the boot files on it. Boot from DVD and reinstall HD files.

it is a hard disk error. most likely your hard disk is defective since is it not registering well. please try to use 80-pin interface cable to correct the problem or change your Hard Disk

press F2 to get into the dell bios and be sure the HDD is listed as first to boot, Then if restart turns the same error, press F10 and run the pre-boot system assesment check. if error 0141 appears, your HDD is failing and needs to be replaced

This error can be a couple of things. If the "boot block" on the disk has become faulty, the system won't recognize that the disk has an operating system on it and will generate this error message. If the disk is defective completely, the same error will occur. If you have a boot floppy or CD, try re-writing the boot block on the disk. If that fails to resolve the problem, the disk is defective and will need to be replaced.
