Installing a dual-boot system can be a complex process, and it's not uncommon for issues to arise. In this article, we'll explore the common problem of Windows 10 failing to boot after installing Ubuntu 24.04. We'll delve into the possible causes, provide troubleshooting steps, and offer solutions to help you resolve this issue.

Windows 10 is unable to boot after installing Ubuntu 24.04 as a dual-boot system. This issue can be caused by a variety of factors, including:

UEFI vs. Legacy Boot Mode: If your system is set to UEFI boot mode, but your Ubuntu installation is configured for Legacy boot mode, it can cause Windows 10 to fail to boot.
Boot Partition Issues: The boot partition is responsible for loading the operating system. If the boot partition is not properly configured or is corrupted, it can prevent Windows 10 from booting.
GRUB Configuration: GRUB (Grand Unified Bootloader) is the default bootloader for Ubuntu. If the GRUB configuration is not properly set up, it can cause Windows 10 to fail to boot.
Partition Table Issues: The partition table is responsible for defining the disk layout. If the partition table is not properly configured or is corrupted, it can prevent Windows 10 from booting.

To troubleshoot the issue, follow these steps:

Step 1: Check the Boot Mode

UEFI Boot Mode: If your system is set to UEFI boot mode, ensure that your Ubuntu installation is also configured for UEFI boot mode. You can check the boot mode by pressing the F2 key during boot-up and navigating to the Boot Mode settings.
Legacy Boot Mode: If your system is set to Legacy boot mode, ensure that your Ubuntu installation is also configured for Legacy boot mode.

Step 2: Check the Boot Partition

Verify the Boot Partition: Use the lsblk command to verify the boot partition. The boot partition should be labeled as /boot or /boot/efi.
Check the Boot Partition Size: Ensure that the boot partition is large enough to accommodate the bootloader and other essential files.

Step 3: Check the GRUB Configuration

Verify the GRUB Configuration: Use the sudo update-grub command to update the GRUB configuration.
Check the GRUB Menu: Ensure that the GRUB menu is properly configured and that the Windows 10 entry is present.

Step 4: Check the Partition Table

Verify the Partition Table: Use the sudo parted -l command to verify the partition table.
Check for Corruption: Ensure that the partition table is not corrupted or damaged.

Based on the troubleshooting steps, the following solutions can be applied:

Solution 1: Reconfigure the Boot Mode

UEFI Boot Mode: If your system is set to UEFI boot mode, ensure that your Ubuntu installation is also configured for UEFI boot mode.
Legacy Boot Mode: If your system is set to Legacy boot mode, ensure that your Ubuntu installation is also configured for Legacy boot mode.

Solution 2: Reconfigure the Boot Partition

Verify the Boot Partition: Use the lsblk command to verify the boot partition.
Check the Boot Partition Size: Ensure that the boot partition is large enough to accommodate the bootloader and other essential files.
Resize the Boot Partition: If the boot partition is too small, resize it to accommodate the bootloader and other essential files.

Solution 3: Reconfigure the GRUB Configuration

Verify the GRUB Configuration: Use the sudo update-grub command to update the GRUB configuration.
Check the GRUB Menu: Ensure that the GRUB menu is properly configured and that the Windows 10 entry is present.
Reinstall GRUB: If the GRUB configuration is corrupted or damaged, reinstall GRUB using the sudo grub-install command.

Solution 4: Reconfigure the Partition Table

Verify the Partition Table: Use the sudo parted -l command to verify the partition table.
Check for Corruption: Ensure that the partition table is not corrupted or damaged.
Recreate the Partition Table: If the partition table is corrupted or damaged, recreate it using the sudo parted command.
