3.14 Fred's case solutions

📌 Fred’s case

• BIOS legacy
• you can have MBR 3P+E
• or GPT with 4P with MBR protective

✅ First step: backup

• always take
  • C:\Users\<user>\downloads
  • C:\Users\<user>\documents
  • C:\Users\<user>\desktop
  • C:\Users\<user>\music
  • C:\Users\<user>\video
  • C:\Users\<user>\pictures
• use a backup engine(backup application)
• copy the six folders
• after formating the computer
• and save that backup again in the same exact place as it was
• 👍🏻 avoid broken links

✅ Disk: MBR or GPT

• MBR
• cannot be GPT because we need more than 4 partitions

✅ How many, size, type of partitions

☑️ Primary partitions

• ✔️ 1P: MSR
• booting for windows
• size: 300MB

• NTFS

• ✔️ 2P: C
• kernel for windows
• size: 16GB(min) + 5GB(extra for updates) + 9GB(extra to keep previous files)
• = 30GB(for Windows 10 Home 32 bits)
• NTFS

• ❓ why primary: bc windows like primary

• also Fred had files in C:/Users/<user>/downloads, desktop, music, documents...
• so add 9GB extra for keeping things in the location where they are

❓ Why do we have to give extra 9GB above 21GB in kernel for windows?
- bc normal users save their files on desktop,
- we are going to change the C format, but we should keep their old files
- so in order to keep the previous files where it was

➡️ old files stay inside C:/
- and you can convince the user to save data in D:/

• ✔️ 3P: / (root)
• linux kernel
• we give primary to linux so linux and windows are balanced
• It could be logical, but as we have a primary, we can store it here
• Lubuntu 18.04
• size: 8-10GB + 5GB(for updates) = 15GB
• format: ext4

☑️ Extended partitions

• size of extended partition: 100GB - 300MB - 30GB - 15GB = 54GB and 700MB

• ✔️ L1: /boot
• in terms of partition orders, give booting the first partition available
• 300MB

• ext4

• ✔️ L2: D
• data for windows
• version hopping
• 10GB

• NTFS

• ✔️ L3: /home
• data for linux
• distro hopping
• 10GB

• ext4

• ✔️ L4: SWAP
• in terms of partition orders, order does not matter

• 4GB

• ✔️ L5: Tunneling
• 4GB
• tunnels, if they are for small files, recommended 4GB
• FAT32

☑️ Unallocated

• ❓ Why is unallocated inside the umbrella?
• bc if it is outside, we cannot reach it

• MBR can only have up to 3P + E

• size: rest of the disk, do 100GB - all the partition size before
• format: no format, this is unallocated

✅ OS

• ✔️ Windows 10
• Home edition

• OS 32 bit

• ✔️ Lubuntu version, year
• as windows is 32 bits, linux should also be 32 bits
• the latest lubuntu with 32 bits is 1904, but this version does not have technical support
• so the answer is lubuntu is 18.04 LTS

📌 Perfect schema for computer with legacy

📌 How to expand to a bigger disk, more than 100GB

• If I have 1TB, instead of 100GB

• and I want to install Windows 10 32bits

• ✔️ P1: MSR

• size: stay as 300MB

• ✔️ P2: C for kernel

• size: stay as 30GB

• ✔️ P3: linux kernel
• size: 15GB

• 👉🏻 booting, kernel size stay

• ✔️ L1: linux boot

• size: stay 300MB

• ✔️ L2: windows data

• size: give more, maybe 300GB

• ✔️ L3: linux data
• size: give more, maybe 500GB

• give more than linux if you are going to use more linux than windows

• ✔️ L4: SWAP

• RAM is 4, so SWAP should be 4GB

• ✔️ L5: tunnel
• size: give more if you really use it
• size: 4GB
