What is MBR or GRUB and why does my system fail to boot?

MBR (Master Boot Record) and GRUB are critical boot components responsible for starting your operating system. If they become corrupted due to updates, disk errors, or OS reinstallations, the system may fail to boot entirely.

Can a corrupted GRUB prevent access to my data?

Yes, a broken GRUB loader can block system startup, but your data usually remains intact. Our repair process focuses on restoring boot functionality without affecting stored files.

Do you repair MBR and GRUB on both Linux and Windows systems?

Absolutely. We repair boot issues on Linux (GRUB, GRUB2) and Windows systems (MBR, BCD), including dual-boot and multi-OS configurations.

What usually causes MBR or GRUB corruption?

Common causes include failed OS updates, disk cloning errors, accidental partition changes, power outages, malware, or installing another operating system over an existing one.

Can you fix boot issues on remote servers or VPS machines?

Yes. We provide remote MBR and GRUB repair for dedicated servers, VPS, and cloud instances using recovery environments and console access.

How long does an MBR or GRUB repair usually take?

Most repairs are completed within 30–90 minutes, depending on disk layout and system complexity. Emergency and after-hours service is also available.

Can you help prevent future boot failures after repair?

Yes. After repair, we verify disk health, correct boot order, rebuild configurations, and provide recommendations to prevent future bootloader corruption.
