More Than 1 OS

[GabD]

When I boot my old compaq presario r3000, it gives me four operating systems to boot from.

It says:

Highlight The Operating System You Want To Boot Into

Windows® Codename Longhorn

Windows® XP Professional

Windows® Vista

Windows® XP Home Edition

I only want to keep Codename Longhorn.

How do I remove the other OS's?

Longhorn was an internal name used by Microsoft when Vista was under development.  MS stopped supporting it in any way a long time ago.  There is nothing available for this anymore -- no drivers, no apps, no antivirus.  Why on earth would you want to keep something that has been obsolete for such as long time?

No. i meant that i just want to keep one operating system.

And also i want to keep longhorn because i love beta windows stuff.

For example, i want to only keep one operating system. How do i remove the others?

There are two things to be done:

1) Removing the boot entries

2) Removing the OSs

In terms of the first, download and install EasyBCD from here:  https://neosmart.net/EasyBCD/

When you run that, select Edit Boot Menu and when the page opens, select the OSs you don't want and delete them.

Then click the Save Settings button.  When you reboot, those OSs will no longer be seen and Windows is likely to boot directly into the OS as it only presents a selection menu when there is more than one OS on the drive.

In terms of the second, download and install MiniTool Partition Wizard from here:  https://www.partitionwizard.com/download.html

When you run that, it will list all the partitions on all the drives.  Select the ones you don't want and delete them.

When that is done, reboot and you can then use the same tool to either expand the current OS partition into the now empty space, of create a new partition to fill that space.
