Hello Rick Sypriano,

When a system takes significantly longer to boot after a hard drive size increase, the issue is usually tied to how Windows interacts with the disk partitions and boot configuration. Extending or resizing a drive can sometimes cause fragmentation in the EFI System Partition or misalignment of the boot volume. This results in delays during POST and Windows initialization.

The first thing to check is whether the boot partition is still properly aligned. Open an elevated Command Prompt and run bcdedit /enum all. Verify that the device and path entries for {bootmgr} and {default} point to the correct partition (usually partition=C:). If they are pointing to a recovery or secondary partition, Windows will spend extra time redirecting during startup.

Next, confirm that the disk is healthy. Run chkdsk C: /f /r and allow it to complete. A resize operation can leave behind bad sector mappings or inconsistencies in the NTFS metadata, which will slow down boot. Also, check the fragmentation level with defrag /C /H /U /V. If the system drive is heavily fragmented after the resize, defragmentation can reduce boot time.

Another common cause is that the page file or hibernation file was expanded incorrectly. Go to System Properties > Advanced > Performance Settings > Advanced > Virtual memory and ensure the page file is set to “System managed size.” If it is locked to a fixed size that no longer matches the new disk geometry, boot can stall while Windows attempts to allocate space.

Finally, check Event Viewer under Applications and Services Logs > Microsoft > Windows > Diagnostics-Performance > Operational. Look for Event ID 100 (Boot Performance Monitoring). This will show you exactly which driver or service is delaying startup. Often after a disk resize, storage drivers such as storport.sys or third-party disk utilities cause delays.

If you provide me with the exact error messages or Event Viewer entries, I can pinpoint the root cause more precisely. Without that, the most likely resolution is correcting boot configuration with bcdedit, running chkdsk, and ensuring virtual memory settings are system-managed.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
