Summary

I was caught out by the wrong partition table type, and took some time to figure it out. I'm running on Fedora, so couldn't use the new USB creator tool that is a debian binary. Updated the "important" section to specify the partition table type.

Without following this step, running make_bootable_linux fails on its pre-flight checks.

Summary by CodeRabbit

• Documentation
  • Updated the Unraid OS manual installation guide with clear instructions to use the MBR/MS-DOS partition table when preparing a USB flash drive, ensuring compatibility with common partitioning tools on Linux and macOS.

Walkthrough

The documentation for the manual installation of Unraid OS has been updated. A new instruction clarifies that users must select the MBR/MS-DOS partition table when formatting the USB flash drive. This update is added to prevent issues with modern partitioning tools that default to GPT, ensuring compatibility with the installation process. No changes have been made to the exported or public entities.

Poem

Hoppin’ through docs, I found a clue,
A twist in the tale for drives anew,
“MBR is the way!” the update sings,
Preventing errors that GPT might bring,
I’m a bunny of code with a joyful view! 🐇✨

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

15-16: Clear and Essential Addition of Partition Table Guidance

The new instruction clearly informs users that they must select the MBR/MS-DOS partition table type, explicitly warning that many modern tools default to GPT—which would cause the installation process (e.g., the make_bootable_linux command) to fail. This change directly addresses the issues raised in the PR description.

Suggestion: Consider adding a brief note about the potential failure (or error message) if GPT is inadvertently selected. This additional context could further help users understand the criticality of choosing the correct partition table type.
