There are several storage device issues that can prevent a computer from starting up properly. The most common storage devices in a computer are the hard drive, solid state drive, and in some cases optical drives like DVD or Blu-Ray drives. Issues with any of these devices during the boot process can lead to startup problems or even prevent the computer from booting entirely.
Hard Drive Failures
One of the most common reasons a computer won’t start up properly is because of a hard drive failure. The hard drive stores the operating system files necessary for the computer to boot, as well as all of your personal files and installed programs. If the hard drive has failed completely, has bad sectors, suffered logical errors like file system corruption, or is stuck in a frozen state, it will prevent the computer from booting up correctly.
Some common hard drive startup issues include:
- Hard drive not detected in BIOS
- Missing operating system error message
- Hard drive detected but stuck on boot screen
- Blue screen errors mentioning hard drive issues
- Operating system failing to load with disk read errors
- Hard drive making clicking or beeping noises
Many times these startup issues are caused by mechanical or electronic hardware failures within the hard drive itself. Problems with the drive’s printed circuit board (PCB), read/write heads, spindle motor, or onboard cache can lead to not being able to access the necessary boot files on the drive.
However, logical damage like file system corruption, master boot record (MBR) corruption, or problems with the operating system core files can also prevent the computer from booting up. This logical damage can sometimes be repaired with boot recovery tools or disk utilities.
Solid State Drive Failures
Solid state drives (SSDs) can also have issues that prevent the computer from starting up properly. Unlike hard drives, SSDs have no moving mechanical parts but they still rely on electronic circuits and memory chips to store data.
Some of the potential SSD boot issues include:
- SSD not detected in BIOS
- Operating system fails to load, hangs on boot screen
- BIOS error messages related to SSD
- Blue screen mentioning solid state drive
- No operating system found message
These startup problems typically occur when the SSD has completely failed, has corrupted firmware, or has failed memory chips/controllers. Because SSDs lack moving parts, the issues tend to be electronic in nature versus mechanical with hard drives. Logical errors like file system corruption can also affect SSD boot up.
Optical Drive Issues
Boot issues related to optical drives like DVD or Blu-ray drives are less common these days. But in some cases, a computer may fail to boot properly if you’re trying to boot from a CD or DVD but the optical drive has failed or is having issues reading the disc.
Some example boot scenarios that could be affected by a bad optical drive include:
- Booting from a bootable operating system CD or DVD
- Booting from a recovery disc
- Booting from an optical disc backup image
If the optical drive has issues reading data off the disc, is making unusual noises, is not spinning up, or is outright failing to work, then this can result in boot errors, missing operating system messages, or the computer getting stuck at the boot screen.
Optical drive problems are not as common these days since many computers no longer come equipped with DVD/CD drives. But they can still be a factor in startup issues when trying to boot from an optical disc.
Causes & Solutions
There are a few root causes that can lead to storage device failures resulting in startup issues:
- Mechanical failure – Issues with the mechanical components in a hard drive or optical drive from normal wear and tear or defects.
- Electrical failure – Electronics components on the disk’s PCB or controller failing.
- Firmware bugs – Bugs in the drive’s firmware can sometimes cause malfunctions or freeze-ups.
- Power surges – Electrical power spikes or surges can damage storage device electronics.
- Logical corruption – File system or partition table corruption that prevents accessing data.
When faced with a computer that fails to startup properly due to storage device issues, there are a few typical solutions:
- Replace the failed hard drive or SSD and reinstall the operating system.
- Repair the corrupted boot files if the issues is logical and not physical.
- Update the device firmware or BIOS to fix bugs.
- Try removing peripherals in case of conflicts or isolation issues.
- Use data recovery tools to rescue files before replacing a failed drive.
Replacing a failed storage device or re-installing the operating system is often the most reliable way to get a computer back up running properly after startup issues. But troubleshooting the specific cause can help resolve the problem without replacing components in some cases.
Hard Drive Startup Issues
Hard Drive Not Detected in BIOS
If the BIOS does not detect the hard drive on bootup, this typically indicates the drive has completely failed or is not getting power/connections. Some troubleshooting tips include:
- Check cabling from hard drive to motherboard
- Try a different SATA cable if possible
- Reset BIOS to default settings (in case a setting changed)
- Listen for clicking noise indicating mechanical failure
- Replace hard drive if no signs of life or not recognized
Missing Operating System Error
Error messages about a missing or invalid operating system usually indicate the drive cannot find the actual operating system files to boot from. Potential solutions include:
- Check cables to hard drive are secure
- Repair or replace damaged master boot record (MBR)
- Reinstall operating system files
- Replace hard drive if physical failure is suspected
Hard Drive Detected But Stuck on Boot
If the hard drive is listed in BIOS but the system hangs on the boot screen, this points to file system damage or corrupt operating system files. Options to try:
- Use bootable recovery media to access disk
- Run CHKDSK or hard drive repair utility
- Reinstall/repair boot loader like master boot record (MBR)
- Wipe and reinstall operating system
Blue Screen Errors Mentioning Hard Drive
Blue screen errors pointing specifically to issues like “BAD_SYSTEM_CONFIG_INFO” or “CRITICAL_PROCESS_DIED” related to hard drive failures usually indicate file system corruption. Fixes can include:
