The Machine That Finally Wake Up

说明与用途

由于文件系统损坏导致启动失败，通过手动重建引导加载程序和运行fsck修复；在干净机器上安装JAZZ；验证GPU性能；修复隐藏假设。

问题

A dual‑boot laptop failed to boot, showing only a black screen due to filesystem corruption and bootloader damage.

结果

Filesystem corruption was fixed, JAZZ installed on a clean machine, GPU performance validated, and hidden assumptions were uncovered and resolved.

工作流

• Rebooted laptop and observed black screen
• Booted from USB and chrooted into broken system
• Rebuilt bootloader manually
• Ran filesystem check (fsck) and confirmed clean
• Rebooted and verified system booted
• Rented an RTX 4090 cloud instance to benchmark GPU performance
• Installed JAZZ on a fresh Windows‑only laptop using public repo
• Repeated installation until all seven failures were resolved
• Documented shutdown bug caused by wrong login session attachment

证据

The black screen eventually turned out to be filesystem corruption.

I rebuilt the boot files manually and ran a filesystem check.

The instance I chose was supposed to have what I needed installed. It did not.
