What Is Bootable Disk and What Is Bootable Disk Used for?
Bootable disk is a kind of hard disk which contains system files, boot files, drivers, etc. items necessary for booting a computer up. The computer can be one whose installed OS fails or still work well, or the computer can be a bare metal. In other words, bootable disc is a portable system drive which can be used to boot machine up in emergency, especially when the machine’s original operating system is crashed and the data on the machine need to be moved out in case of data loss.
Since bootable disk is based on bootable system and there are two common multi-applied computer systems (Windows and Linux), there are also two kinds of bootable discs – Windows PE bootable disc and Linux bootable disc.
How to Create Bootable Disk?
AOMEI Backupper allows you to create both Windows PE (WinPE) and Linux kernel based bootable disc easily, to be used as rescue media for emergency usage.
Note:To create a bootable disc, you need to prepare blank CD/DVD-R/RW discs, USB media or external hard disk which can be written to and plug it into your computer. Besides, make sure there is no data or no important data saved on these devices for creating bootable disk will overwritten these devices for storing system files. If there does be crucial data, copy them out to another safer place.To create a bootable disc with AOMEI Backupper, first of all, download, install and open AOMEI Backupper on your computer.

We suggest you create a bootable disc based on Windows PE, which provides more flexible and convenient operations than a Linux bootable disc.
Create Windows PE Bootable Disc
1. Select "Windows PE" and click "Next" button. AOMEI Backupper will check whether your system meets the corresponding requirements. If not, you may need to install Windows AIK. Learn more about Windows AIK and how to install it.

4. Wait for the process to complete and click "Finish".
Create Linux Bootable Disc
Creating a Linux bootable disc is similar to the steps of creating Windows PE bootable disc. The only difference is that you can create this kind of bootable disc without meeting any requirement, so there will be no need to download and install Windows AIK. However, as mentioned, a Linux bootable CD might be less compatible.
- AOMEI Backupper allows you to manually add additional drivers when creating a Windows PE bootable disc.
- If you choose to create an ISO image file, make a note of the path where you saved the image file so you can easily find it subsequently.
After you complete creating the ISO file, you can manually burn it to a CD/DVD/USB device. Windows 7 and later has an integrated burning utility; you can invoke this by right click on the .iso file, and select -> Open with -> Windows Disc Image Burner. Alternatively you can use 3rd-party burning software. For more guidance please follow the tutorial on how to burn ISO file to CD/USB.
To create X86 system bootable disk, you just need a 32-bit operating system.
After you successfully creating bootable disk, when can it be put into usage? As mentioned in the start, you need to make use of a bootable disc when your current system fails to boot up. When you rely on the bootable device to boot the computer up, you can on the one hand migrate the important data out, on the other hand restore OS back from former created system image.
