You can address this by checking the hardware connections and ensuring everything is properly seated. The issue might stem from a loose or faulty component. Since you can access the drive using your brother’s computer, verify the boot settings and USB configuration. The settings remain consistent after a restart, which suggests the problem isn’t with the OS but possibly with the physical drive or power supply. Replace the battery if it’s weak or failing, as this could affect boot stability.
It's common to request comprehensive system details during troubleshooting, since hardware issues can arise unexpectedly. So far, no specific quirks have been encountered. A CMOS battery is built into the motherboard itself; instructions are available here: https://www.intel.ca/content/www/ca/en/s...ssors.html. Choose the option to clear CMOS using the battery method as described. If that doesn't resolve the problem, consider a full system repair to address the MBR, as suggested by @Zaquria. Should the bootable USB fail to start, verify the BIOS settings for USB options.
Yes, it's common to overlook specific details like CPU, SSD, RAM, or BIOS version. In the OP example, those factors didn't matter. What changes the situation is a single configuration item that stands out—often related to hardware design or hidden settings.
