formatting a VHD

No problems formatting a Virtual Hard Drive in Virtual Box program. It will even say "formatting c: drive" and scare you until you realize and remember it's just a VHD file, not your entire physical drive. If you want to install Linux in a VDI or VHD, then don't even bother to format it first. Just create it and then from the ISO file run the Linux distro as a virtual CD/DVD while in Virtual Box program, and let the install program see the virtual drive you created and it will continue to do all the formatting if you use the default install, or you can choose "something else" and manually adjust things as wanted for the install. I would suggest using the 32 bit Linux versions for use in Virtual Box instead of the 64 bit ones.

thnx for answer,. i still have some confusions...

thnx for ur answer........
but i still have a little question.

so my process will be like this. (1)-instald vbox (2)-download linux 32 bit (3)-create new settings in vbox like shown in the youtube videos...(4)run the linux iso from there??

another question.. a folder or directory works like a VHD? and when it says formatting,, does it actually formats that folder?
to be able to use the vhd thing do i need to have an extra storage device like a pendrive or secondary hard disk??

thnx in advance

virtual box

Anything you do in Virtual Box uses files and ISO files, not drives or real partitions on the drive, at least not directly.

You can mount ANY ISO file. Those which would burn as "bootable" to a CD or DVD can also be used as a mounted bootable ISO file in Virtual box.

You first add a controller, either IDE or SATA. To that controller you can add a CD drive. You can then use either your physical CD drive or link to an ISO file.

You can also create a virtual hard drive. You add a virtual drive to the controller (IDE or SATA). You then link that virtual drive spot to the virtual hard drive you created, which in reality is a file.

You then set which one you wish to boot from, the CD or the virtual hard drive.


Here is one I have an bootable ISO of Mint 17 with an IDE controller and my physical CD drive set for SATA controller. I can choose to boot from either, such as putting some other CD or DVD in the physical drive.

In this one, I have window 10 already installed to a VDI file, which is a "hard drive" on SATA controller so far as windows 10 is concerned. On an IDE controller I have the physical CD drive. In this setup I could boot instead to the CD drive with a Windows 10 DVD in it, and then use that to install to the VDI (virtual drive) which I'd created. One has to make sure the size of the VDI or VHD is large enough for what's to be installed on it too.

Notice the yellow !, because in this case it only means I've shared MORE THAN half my RAM to the Virtual Operating System, which I can easily do since the Host system is Linux and runs itself and Virtual Box on about 1 GB to 1.5 GB of RAM, leaving the rest for the Guest system.

Here you can see windows 10 opened and running in it.

I don't think there is

I don't think there is any risk using VM. It only but consumes disk space while using it.

VM virtual box is cool

Nah is cool is like vmware just free, the program takes care of everything, is like having a pc inside another pc, and OS inside another OS, without having to partition your hard disk, if you want to know more you can check out youtube there is a tons of videos of how to use VMvirtual box like installing a new OS all the steps. IS pretty easy and fast installing a new OS like linux would take like 30 minutes at least, give it 10 GB of space to your virtual hard disk if you just want to try it out if is something more like 20 GB, you could visit too this web page it has a lot of stuff like ebooks and tutorials
