If you’re encountering the error message Hard Drive – Not installed on your Windows 11 or Windows 10 computer, then this post is intended to help you. In this post, we will identify the possible causes, as well as provide the most appropriate solutions you can try to help you remediate this issue.

Hard Drive - Not installed

As per user reports, you’re most likely to encounter this error on an HP, Lenovo, or a Dell computer.

There are several reasons why your Dell computer reports no hard drive installed, detected or missing operating system error on startup:

  • Bad BIOS setting.
  • A loose cable.
  • A corrupted hard drive registry.
  • A bad Windows installation.
  • A boot sector virus.
  • A broken hard drive.

If you’re faced with this Hard Drive Not installed problem on Windows 11/10, try this first:

  • Unplug the system and remove the base cover.  Disconnect the battery and hard drive.  Then hold the power button for 30 sec. Reconnect both and power up – check to see if the drive is recognized.
  • If it’s not, and the system is under warranty – call Dell for a drive replacement.

However, if you wish to do a bit of troubleshooting yourself, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

  1. Continuously press the F1 key
  2. Check BIOS setting
  3. Check hard drive cable
  4. Perform PC hard reset
  5. Test the Hard Drive for physical damage
  6. Perform a Windows Repair Install

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Continuously press the F1 key

If your Dell computer shows the Hard Drive – Not installed error, you can press F1 to continue. It is a BIOS error message. Pressing F1 is a contingency procedure that can work around an error, and the computer may load into Windows correctly after pressing F1.

2] Check BIOS setting

BIOS handles the basic setup and boot process for the computer and prepares it to load the operating system. Hard drives are usually connected to onboard a SATA or IDE port. If the port that the hard drive is connected is disabled, the hard drive will not be detected by the computer and you will get Hard Drive – Not installed error message. In this case, you need to check or reset the BIOS setup and also ensure that the hard drive is on top of the list in the boot priority.

3] Check hard drive cable

You may encounter this error if the computer isn’t physically connected to the hard drive. So you can check the hard drive cable to ensure whether it has a loose cable connection or the SATA cable and power cable may have worn out. If it is, you can reconnect the cables from both the hard drive and the MOBO, or replace the cable with a new one.

4] Perform PC hard reset

A hard or forced reset erases all information in the computer memory and might restore functionality. Resetting your computer forces the system to clear and reestablish the software connections between the BIOS and the hardware.

Do the following:

  • Turn off the computer.
  • Remove the computer from any port replicator or docking station.
  • Disconnect all external devices from your computer, unplug the AC adapter from the computer.
  • Remove the battery from the battery compartment.
  • Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
  • Insert the battery, and plug the AC adapter back into the computer, but do not connect any of the peripheral devices such as USB storage devices, external displays, printers, etc.
  • Turn on the computer.
  • If a start menu opens, select Start Windows Normally with arrow keys and hit Enter.

5] Test the Hard Drive for physical damage

Remove the hard drive from the computer and connect it to another computer to see whether it still works. if it doesn’t, you should replace the hard drive with a new one. If it does, you can test the hard drive to see if it has bad sectors.

6] Perform a Windows Repair Install

A bad Windows installation may cause errors and prevent Windows from loading. Consequently, the Dell computer may show this error when booting. In this case, you can try running a repair installation to fix it. If Windows sees the hard drive when running a repair install, the drive is probably not broken.

If the repair install doesn’t work, the drive may be infected with a boot sector virus, which you need to fix by formatting the hard drive.

Killexams : Heat Gun GPU Reflow Fixes Laptop

Solder connections on processors seem to be a very common failure point in modern electronics. Consider the Red Ring of Death (RRoD) on Xbox 360 or the Yellow Light of Death (YLoD) on PlayStation 3. This time around the problem is a malfunctioning Nvidia GPU on an HP Pavilion TX2000 laptop. The video is sometimes a jumbled mess and other times there’s no video at all. If the hardware is older, and the alternative to fixing it is to throw it away, you should try to reflow the solder connections on the chip.

This method uses a heat gun, which we’ve seen repair PCBs in the past. The goal here is to be much less destructive and that’s why the first step is to test out how well your heat gun will melt the solder. Place a chunk of solder on a penny, hold the heat gun one inch above it and record how long it takes the solder to flow. Once you have the timing right, mask off the motherboard (already removed from the case) so that just the chip in question is accessible. Reflow with the same spacing and timing as you did during the penny test. Hopefully once things cool down you’ll have a working laptop or gaming console again.

Killexams : Major test of first possible Lyme vaccine in 20 years begins

DUNCANSVILLE, Pa. (AP) — Researchers are seeking thousands of volunteers in the U.S. and Europe to test the first potential vaccine against Lyme disease in 20 years -- in hopes of better fighting the tick-borne threat.

Lyme is a growing problem, with cases rising and warming weather helping ticks expand their habitat. While a vaccine for dogs has long been available, the only Lyme vaccine for humans was pulled off the U.S. market in 2002 from lack of demand, leaving people to rely on bug spray and tick checks.

Now Pfizer and French biotech Valneva are aiming to avoid previous pitfalls in developing a new vaccine to protect both adults and kids as young as 5 from the most common Lyme strains on two continents.

“There wasn’t such a recognition, I think, of the severity of Lyme disease" and how many people it affects the last time around, Pfizer vaccine chief Annaliesa Anderson told The Associated Press.

Robert Terwilliger, an avid hunter and hiker, was first in line Friday when the study opened in central Pennsylvania. He’s seen lots of friends get Lyme and is tired of wondering if his next tick bite will make him sick.

“It’s always a worry, you know? Especially when you’re sitting in a tree stand hunting and you feel something crawling on you,” said Terwilliger, 60, of Williamsburg, Pennsylvania. “You’ve got to be very, very cautious.”

Exactly how often Lyme disease strikes isn't clear. The Centers for Disease Control and Prevention cites insurance records suggesting 476,000 people are treated for Lyme in the U.S. each year. Pfizer’s Anderson put Europe’s yearly infections at about 130,000.

Black-legged ticks, also called deer ticks, carry Lyme-causing bacteria. The infection initially causes fatigue, fever and joint pain. Often -- but not always -- the first sign is a red, round bull's-eye rash.

Early antibiotic treatment is crucial, but it can be hard for people to tell if they were bitten by ticks, some as small as a pin. Untreated Lyme can cause severe arthritis and damage the heart and nervous system. Some people have lingering symptoms even after treatment.

Most vaccines against other diseases work after people are exposed to a germ. The Lyme vaccine offers a different strategy — working a step earlier to block a tick bite from transmitting the infection, said Dr. Gary Wormser, a Lyme expert at New York Medical College who isn’t involved with the new research.

How? It targets an “outer surface protein” of the Lyme bacterium called OspA that’s present in the tick’s gut. It’s estimated a tick must feed on someone for about 36 hours before the bacteria spreads to its victim. That delay gives time for antibodies the tick ingests from a vaccinated person’s blood to attack the germs right at the source.

In small, early-stage studies, Pfizer and Valneva reported no safety problems and a good immune response. The newest study will test if the vaccine, called VLA15, really protects and is safe. The companies aim to recruit at least 6,000 people in Lyme-prone areas including the Northeast U.S. plus Finland, Germany, the Netherlands, Poland and Sweden.

They’ll receive three shots, either the vaccine or a placebo, between now and next spring’s tick season. A year later, they’ll get a single booster dose.

“We’re really looking at something that’s a seasonal vaccine,” Anderson said, so people have high antibody levels during the months when ticks are most active.

Volunteers can be as young as 5 and should be at high risk because they spend a lot of time in tick-infested areas, such as hikers, campers and hunters, said Dr. Alan Kivitz who heads one of the study sites at Altoona Center for Clinical Research in Duncansville, Pennsylvania.

Killexams : HP Chromebase All-in-One 22 review

HP Chromebase All-in-One 22: Two-minute review

The HP Chromebase All-in-One 22 is helping usher all-in-one PCs into the mainstream market, and it’s about damn time. Even now, most AIO PCs on the market are pricey and tend to target professionals who need a minimalist yet powerful solution for their demanding computing workloads. 

That isn’t to say that there aren’t all-in-one computers on the market that are affordable enough to the general public. But, you also have to dig deep to find them, as the likes of the iMac (24-inch, 2021) and the HP Envy 34 All-in-One tend to outshine them all.
