  1. Multiboot System under Windows XP – Ubuntu – Windows 7 Qiong LIN - 28 April 2012

  2. Multiboot Mutlibooting means to host multiple Operating Systems (OS) on one single computer

  3. Why Multibooting ? • Some softwares run only under one specific operating system (ex: Windows or Linux) • Tests running on different environments within one machine • Efficiency and cost savings on hardware • Migration to a new operating system

  4. Step into … Multibooting Process • Preparation beforehand: partitioning • Installing new operating systems • Select and launch one of those operating systems

  5. Step 1 - Partitioning Partitioning is the process of dividing an entire storage device into smaller chunks Rules to keep in mind: • Size & structure • File system specific to OS’s in use

  6. Partitioning – Size and Structure Size • Allocate sufficient space depending on new OS and future uses Structure of the partition: • Primary partition ( max 4 units) • Extended partition (> 4 units), which leads to: • Logical volume

  7. How to partition ? • Issue: computer hard drive mounted -> not modifiable • Solution: use a Live CD (System Rescue CD) Before Partioning Partitions finalised

  8. Partitioning – File systems Assign the right file system to each partition: • NTFS -> Windows file system • ext4 -> Linux file system

  9. Step 2 – Installation ongoing … Three OS’s are installed in this order: • Windows XP • Ubuntu • Windows 7 …. Installations done!

  10. Step 3 – Multibooting process • BIOS -> sends INT 13h -> 1st sector (MBR) • Customised GRUB multiboot start menu • Load the booting code • Launch the operating system on the selected partition 1st

  11. Data Protection Achieve data security => data encryption

  12. No separation between different OS’s – free access to data Data protection needed …

  13. Data Encryption – two scenarios OS built-inpassword protectedencryption • Linux – pre-installing protection (option on the whole partition/individual files) • Windows XP/7 – individual files Third-partyencryption (TrueCrypt) • Virtual mounted disk

  14. Example: File locally encrypted on Linux

  15. Conclusions • Multibooting -> gain flexibility on number of OS’s available • To better explore the computer capacities • Skills gained: booting, partitioning, OS’s features, different file systems • Becoming conscious about data safeguarding
