Removing one of three O/S.

I have three operating systems on a laptop and would I like to remove one as it does not run software manager.
The original Vista basic is what I use to run some of my old software.
Two Linux O/S.
I want to remove one of the Linux O/S.
If I go to Disk Management and DELETE the partition containing the O/S that I
want to remove what happens.?
Does that action automatically make that partition free and available to the other partitions?

 

Hi, on this subject, I can't support, sorry, but take a look down here in these links, I hope it will be I can be of help.

How to Uninstall Windows or Linux After Dual-Booting
How to uninstall parallel linux distros in a multiboot environment

 

I was hoping it was a simple trick but apparently not.
It`s not urgent so the answer can wait awhile, the computer is getting old but good (essential) for old software.

 

Do not delete a partition. You can have boot problems. And a mistake happens easily.
Never use a Windows partitioner in a hard drive containing Linus partitions. Windows is unable to deal with Linux/Unix, but Linux/unix deals very well with windows partitions....
It's rather simple.
I suppose that the Windows was installed first, and after the 2 Linux OS. it's the best procedure, as Windows has problems when installed on a non virgin hard drive.

What are your Linux OS?
Basically you have only to run 2 softwares;
1- You run the soft "OS uninstaller" from the Linux you want to keep. So no mistake...
After you run the soft Boot Repair from a live CD, it's very simple and straightfoward. Boot repair will rewrite if needed the boot sector and make a new grub with the options of the linux you have kept and Windows.
Boot Repair Live CD is the tool to keep...It solves 99.8% of the boot problems im less than 10 minutes. Search boot-repair-disk A rescue disk that includes the Boot Repair tool
Now you can use the disk partitioner and format the partition which had the deleted Linux OS in NFTS. The best is to use G-parted from your linux OS, or better from a live CD..

If the compu was made before the birth of Buddha, it's better to run all the softs from a rescue Linux live CD as they use minimal resources

With a old computer you have some Linux OS able to run it nicely with a meager 1 mega of memory.

Windows partition hates to be resized. When it accepts, you are going in multiple problems.
That I do I format the freed partition in NFTS, and I use it as partition shared by Windows and the Linux. Very useful for keeping docs, pics, movies etc that you want to access from any of the OS.

Myself I use a very light Windows 7 by obligation, and a complete Mint 18 Sarah, easily the best OS.
The partition in NFTS I have named COMMONS keep all the docs and others I use with the two OS, plus the some essential files saved from each OS. This partition is saved automatically in a second hard drive 3 times a week, and I use MEGAsync to save my data in the cloud at mega.nz with a double encryption with a non American and non Russian soft. I have nothing to hide but I like the idea of the NHS suffering to decrypt my cooking recipes...

 

Thank`s very much for your great explanation which I am sure is the real deal I need.
I have Mint Sara which I like also.
I will print your info and take it to my next computer club meeting so we can share with others. Thank`s again.

 

Tom. You're welcome. I'm happy to have helped. I have used Linux for more than 20 years. Mint 18 is simple, efficient and very powerful with very simple tweaks. Very easy to use for a Windows guy.
You'll see that suppressing an OS is a pretty easy task with the good tools. Rescue Linux live CDs are a must either for Windows and Linux users.

I almost forgot a great tool for mirroring easily hard drives MiniTool Partition Wizard Free 9.1 for Windows. It has function copy partition and copy disk. Il you have a second HDD of same size or bigger than the original HDD (HDD are dirt cheap now) you can copy the entire disk, and to get an exact bootable replica...Works until W7 without problems, after that depends of the caprices of W8 and following which doesn't want to be copied.
So in about 1 hour you get a perfect bootable copy of your HDD with all the installations, softs, data etc of a 500 megas HDD with 2 os and 4 partitions with a modest PC.
The original HDD dies, no problem you throw it, and plug the copy HDD. 10 mn of work and it's done. No time lost in reinstallations, tweaks etc...I have used similar mirroring systems since 1986 and the worst I have lost is 30 mn of work...In my engineering office the main HDD was mirrored every night, and the data of the work copied on another HDD every 30 mn in incremental. No unreliable and slow disquettes, CD and DVD. Never lost an important file even when a computer "burnt" down.
