Multi‑Boot System Startup and Boot Repair

Dual‑booting Windows and Linux, but the boot menu is missing or one system cannot be accessed. Our on‑site boot record repair uses startup repair tools to rebuild the MBR or EFI boot partition and correctly configure GRUB or Windows Boot Manager entries, ensuring both systems boot normally and file systems are mutually visible. Because different partitioning schemes and OS versions lead to varying repair steps – from simple rebuild to manual boot script editing – a deposit is required, and the final fee is based on the actual repair operations and verification time.
