Unable to boot from the old SSD on the new laptop.
Unable to boot from the old SSD on the new laptop.
Hello. I recently purchased a Lenovo Legion 5 Pro 16th Gen laptop for a hardware upgrade, but it comes pre-installed with Windows 11 (64-bit). I need to use files from my previous machine, which has around 800GB of essential work data that’s hard to reinstall. My old SSD runs Windows 10 (64-bit) and is a SATA drive. I created a clone of it onto a new NVMe M.2 card since the new laptop only supports NVMe. The issue arose when trying to boot from this cloned drive—it isn’t recognized as bootable in BIOS, and I have no way to fix it. I attempted to switch boot modes, disable secure boot, and even changed the disk format from MBR to GPT, but the problem persists. I’ve tried cloning before without issues, so I suspect the process itself might be faulty. I’m unsure if the hardware, software, or both are at fault, or if it’s something entirely different. If anyone has advice or solutions, please let me know. Thank you for your help.
After tackling the GPT challenge, you may encounter blue screens due to outdated device drivers. Begin by restoring the original drive to the original laptop and performing a Sysprep. This will strip OS-level drivers, making it function as if you're using pre-installed Windows 10: https://www.ubackup.com/windows-10/syspr...-6988.html. After powering off, avoid restarting to that drive again. If your new SSD exceeds 2TB, UEFI/GPT becomes essential; otherwise, you can use Legacy Boot or Legacy & UEFI in BIOS. Install Windows 11 and if needed, clone the prepped drive onto the new hardware. Boot from the cloned drive—Windows 10 may install via a licensing workaround (e.g., Windows 10 PE) before proceeding. Upgrading to Windows 11 should resolve any licensing concerns.
Hi, your question is clear. You want to know if you need to modify the MBR to GPT when cloning a disk, especially since you're using a 1TB SSD. Regarding Sysprep, it may have removed some personal files, but it's important that nothing essential from your work data remains. As for BIOS settings, most laptops don't offer a boot mode switch between legacy and UESF, so you won't find that option there.
GPT is required only for storage exceeding 2TB. Make sure to back up any crucial documents beforehand.
