Think it like similar to an ISO file in Windows operating system. A wide selection of user-friendly operating system software is available through both disc installation and download.

#Windows operating system disk install
If you have this System partition on a separate physical hard disk to your copy of Windows you are doubling your chances that a hard disk failure will render your system unusable. It might also be the case that you want to swap this disc out for a larger one, or remove it completely. This can also render your copy of Windows unusable. To boot from the disk, you need to hold down the option key when you hear the boot. If you plan to install both a hard drive and Intel Optane Memory, Windows 10 must be installed on the hard drive. The boot menu resides here, if you don't have this partition you won't be able to start your PC without detailed rebuilding of the boot system, if it's even possible to do so as sometimes it's not. Either way the process is very technical and not for the faint of heart. There's no hard and fast rule here that says you absolutely must install Windows on this drive, in fact it will boot merrily from any hard disk in your PC and from any partition on that drive. Windows often places a 100Mb System partition at the beginning of Disk 0 though. This hidden partition stores the boot information for your PC. It's completely separate from your Windows installation but absolutely critical. These disks are labelled by Windows, Disc 0, Disc 1, Disc 2 and so on with Disc 0 (zero) being the critical one to the operating system. This is the disc on which you really should install your copy of Windows. Pick troubleshoot and chose from these two options restore from the system restore point and. And it will restart your computer in the. Press Windows key + L and restart PC by hitting the shift key while choosing the Power button > Restart. This wasn't a problem even a few short years ago as computers only came with a single hard drive. With the cost of hard drive storage still tumbling though and capacities increasing, it's becoming more and more common to find two hard disks inside a new PC and even some high-end laptops. Connect recovery drive and switch off the computer. This address does exist within Windows but it's well hidden. One time when you will see it though is when you install the operating system and with Windows 7 (and Vista) it is vitally important to make certain you choose the right one. Windows has always had what many people believe to be an unconventional and frustrating method of addressing physical hard disks. I'm talking here about drive letters. These virtual constructs, I can only really describe them as that, are pointers to the actual names of the disks in your computer. This works in a different way to Unix systems where the OS and the user both refer to the actual disk address.
