Boot Error on Ubuntu System

Dual-Boot Issue

A user has reported encountering a boot error message on their Ubuntu system. The system is a dual-boot setup with Windows and Ubuntu 20045 LTS. Upon booting, the user receives the following message:

Error Message

The system is unable to claim resources for a device. A Linux patch exists that can print the resource range of the failed device, which may indicate which process or device driver has already claimed the resource.

Troubleshooting Suggestions

The error message suggests that the kernel is unable to load video drivers. As a troubleshooting step, the user is advised to try booting with the kernel parameter "nomodeset." This parameter disables the kernel's loading of video drivers and uses BIOS modes instead. This may allow the user to boot into the system and investigate the resource conflict further.

Further Investigation

To resolve the issue, the user can use the Linux patch mentioned in the error message to identify the process or device driver that is claiming the resource. Once the conflicting process or driver is identified, appropriate steps can be taken to resolve the conflict and allow the system to boot normally.
