Fix GRUB Dual-Boot Failure

@Shrutibimpl

Hello, I will help you diagnose and repair your dual-boot system configuration so both operating systems load correctly. Since the standard reinstall and Boot-Repair tools failed, the issue is likely a corrupt EFI System Partition structure, redundant boot entries in the motherboard's non-volatile memory, or a partition layout mismatch. I will work with you via a live environment to inspect your GUID partition table, verify the exact mount point of your EFI partition, manually rebuild the EFI boot path structure for both Windows and Linux, and clean up conflicting boot variables using system utilities like efibootmgr to restore proper boot functionality. 1) Is your system partitioned with a GUID Partition Table (GPT) or an older Master Boot Record (MBR) schema? 2) What are the exact Linux distribution and Windows version installed on the dual-boot drive? 3) Do you have access to a secondary computer to create a customized live-boot USB if required during our diagnostic steps? Thanks, Bharat

Hello dear, I am an experienced full-stack developer and Linux systems specialist with 10+ years building and troubleshooting production environments, including bootloader recovery, server maintenance, and enterprise-grade infrastructure support systems repair. Understanding: I understand your dual-boot system is stuck in GRUB rescue, unable to chain-load Linux or Windows despite reinstall attempts, requiring deep diagnosis of EFI boot entries, partition mapping, and GRUB configuration to restore reliable boot functionality properly. My skills include Linux recovery, GRUB repair, EFI boot management, Boot-Repair, efibootmgr, and Ubuntu troubleshooting Feel free to share access details I can fix this immediately Best regards Md.

Hi, I will diagnose your GRUB rescue failure, rebuild the bootloader, and deliver a working dual-boot menu with a written summary of every step taken. Given that a standard chroot reinstall and Boot-Repair both failed, I will first check whether the EFI System Partition is intact and correctly mounted — a corrupted or undersized ESP is a common cause that survives typical repair attempts. I will also verify efibootmgr entries for stale or duplicate boot records. Questions: 1) Is this a UEFI-only setup or legacy/CSM? 2) Which Linux distribution is installed? Ready to start whenever you are. Kamran
