How do you install two different OS in a computer?

Answer 1

Two Operating system can be installed in your PC but it depends on what OS you want to install and in which order

supoose take an example of WINDOWS OS

Win95----> Win98-->Win2000/millennium/NT--->Winsow Xp----> Win Vista

For diffrent OS

Wrong is Linux then window

Correct window then Linux

this is because of file systems difference in each..

Both support diffrent file system and as theOS uprade its file system also upgrades

In the Macintosh Operating system, you have two or more different system folders, and using the Startup Disk/Folder control panel, you select which operating system you wish to use when you restart your computer. This can include Windows emulators that are installed on the Mac.

First of all, whoever wrote the above answer was somewhat lacking in the use of the English language, or their brain was working faster than they could write/type! Totally unclear what is meant! ->"For diffrent (correct: different) OS ... Wrong is Linux then window ... Correct window then Linux" <-

Now, what is that supposed to mean?

Basically, you should use a WINDOWS OS as the PRIMARY OS in the first active partition, with an average size of between 10GB and max. 25GB (allowing for additional programs, updates and the like). For the next OS, you can use either LINUX or a LINUX-based OS, on a separate partition (also active). This partition doesn't have to be as big as the WINDOWS OS, because it's not as bloated as WINDOWS. 8GB to 15-20GB is more than adequate. More than 2 OS, is rather unneccessary, and in the long run, could cause more problems.

: When you install win xp in c: then. again boot through CD. and select instalation drive C: again. then show massage. alreadyu installed. then change windows folder name. after that same procedure.

Answer 2

It sounds as though you have operating systems on separate partitions of the same hard drive. This can happen when an internal hard drive is upgraded from one version of Windows to another. In all likelihood, the hard drive was not formatted before the upgrade.

Answer 3

You would need to partition your hard drive and then do dual boot. The other option is using VMWARE (virtual machine) but that option requires a fair bit of ram and CPU as well as support for Virtualisation. This is due to it actually running both OS's and once.

Answer 4

This is commonly referred to as "dual-booting".

First, you must create two separate partitions on your hard drive using software such a fdisk, gparted, Disk Druid, Partition Magic, etc.

Install each of the operating systems on their own partition, then you must use a boot loader such as Grub, Lilo or the Windows boot loader to select which OS you would like to boot into. The boot loader will usually be an option you can set up during the install process of the second OS.

Answer 5

It's called dule boot, you want to partition your hard drive in half, or how ever big you want them to be then you install your first windows on the first part of your hard drive, then you do the same thing but install it to the second hard drive.

Answer 6

It's usually simply a case of inserting the installation disc into the CD/DVD drive - and letting the computer 'auto-run' the program. If it's a straight-forward install, there's usually very little input from the user until the installation has finished. Depending on the OS, installation can take as little as 20 minutes or as much as 2 hours.

Answer 7

You need to partition the disk. You can then have any OS you wish and boot to the one of your choice.

Answer 8

Partion it first. Each OS will need a serperate partition. After that load the CD for the OS your going to install, and tell it to install to that partion.
