So here I have simply explained how to Ctrl Alt Delete on Mac. You can either use the Mac style which I have explained above or you can customize or change the settings as per your preferences in the second method which I have shown you above. This will help you to force quit an application on Mac.
When you have a problem while using your computer and you receive an error message, you’re hoping the message will point toward the cause and then it can be appropriately rectified. This doesn’t always happen though and the message can be rather generic and the fix isn’t exactly a straightforward affair with a clear place to start troubleshooting. Unfortunately, there seems to be many errors you could encounter on your system that sound straightforward but lead to the same problem, the error message isn’t accurate enough for you to make a clear decision about what to do next. A while back I had a problem with my computer, and after some odd things happening such as a CD-R failing a burn and the computer starting to respond very slow, I decided to shut it down and leave it for a while. When I booted it up the next day, I got the error message: A disk read error occurred. Press Ctrl+Alt+Del to restart. However, the BIOS detected the hard drive just fine.
After an exhaustive search around the Internet and forums, no one had the exact fix for this problem and there doesn’t seem to be one fix to try in preference to any others. What makes this even worse is there are so many different ways to attempt to fix this error, it could take days to get through them all. And to make matters worse, a disk read error might not actually mean there’s a problem with the hard drive itself! Also there seems to be just as many software causes as hardware causes. Listed below are some of the possible solutions we came across to fix the “A disk read error occurred. Press ctrl+alt+delete to restart” problem. Test the Memory This isn’t actually mentioned that much around the web as a solution to the disk read error problem, but believe it or not, this was my problem.
I used a tool called and ran tests on my RAM, and indeed there were problems. After experimenting between different sticks and RAM slots I eventually deduced my RAM slot 2 was damaged because the sticks worked fine in the other slots.
As this is a simple and non destructive test meaning you’re not touching the hard drive risking further damage, it is recommended you try this first. It may sound odd but in fact memory problems can be responsible for a vast array of different errors on a system where testing your RAM might be the last thing you think of. Try the Drive on Another Machine As we’ve said, although this problem sounds like a simple hard drive issue, people around the web have reported that they have traced the problem to faulty video cards, modems, motherboards and even power supplies. The easiest way to rule out any of these is to take the hard drive out and connect it up to another machine or connect it to the same machine via external USB. If you can boot it up past the error or can access all your files without a problem, then the issue will likely be related to other hardware in your machine.
Unfortunately in this case it could be down to trial and error in finding the offending piece of hardware by removing or replacing what you can, although the next possible fix is quite easy. While the drive is connected by another method, it’s recommended to run a scan with something like to test for any bad sectors.
Whether HD Tune finds any issues or not, you should also run a “ chkdsk drivename: /r” from a command prompt while you’re able to or use a. It’s also wise to or while the drive is accessible. Check / Replace Cables Although I haven’t seen SATA cables fail (but obviously they can), faulty IDE cables can sometimes cause issues such as read or write errors on hard drives as well as optical burners. If you have spare cables, you can replace them, or unplug the current cables, inspect for damage, and then reconnect them if OK.
Also try different SATA or IDE ports if you can as there is a possibility of a damaged port. If you get the disk read error after installing a new drive, make sure the hard drive is on the master connector (end of the cable) and if you can, set the hard drive jumper to master instead of cable select. Also try without a secondary (slave) device attached to the same cable if there is one. Resetting / Updating the BIOS In rare circumstances setting the BIOS back to defaults can fix the issue. You can usually get to the BIOS by pressing Del or F2 etc during boot. There should be an option to reset to defaults, look for an option similar to the one in the picture below. Failing that, you can remove the BIOS battery for a few minutes to reset.
If you’re unable to access CMOS because it is password protected, you can easily reset it from Windows by using. Updating to a newer BIOS has also been reported to work, especially on laptops. We have several more possible solutions to the disk read error problem on page 2. Precisely speaking, it occurs due to hibernating your laptop. ITS SOLUTION: Make a bootable windows Repair USB. Boot your system with USB.
Let the process complete.it will show a message ” OS Uninstaller/ uninstall ”. If it automatically uninstalls the window-well and good, if it doesn’t- uninstall it through WinRepair software in the same window manually. When it uninstalls the window then you just install a fresh window.
Problem solved:) THEORY OF THE ISSUE: In hibernating process, the RAM copies its data into the harddrive and upon turning-on laptop, the RAM takes back the data from harddrive. The problem occurs when RAM can’t take back the data from harddrive,hence showing up this msg on black screen.
This morning I had this problem. Yesterday i connected the audio cable from the monitor to the motherboard, but as the sound did not work when the cable was plugged into the motherboard I had to take it out halfway. This morning, when I was turning on computer, the hdd had this problem. I looked at what to do now and I simply pushed the cable to the end and it worked normal. It looks like the problem was with the power going through cable. It sparks at the end of earphones (which was connected to my monitor) several times when i would touched it with my fingers.
I got this error in the Past and I Visited a Computer Repairing Shop and threy Fixed it. But 1 day ago, I got this Problem again When I used Memtest 86+. The test did run Well at First but When I Move my 2GB RAM Into Slot #2, Then My PC did’nt even Start so I moved to Slot #1 Again and then I got this Error. I tried Memtest 86+ again and then My PC runs back at Normal.
After that, I used all the Tools You mention in this Post but My Hard disk is Fine. And I don’t think there is any Cable issue because I never touched that Part and as I told You My PC runs back at Normal by doing Just Pass 1 of Memtest 86+ again. I had reset my BIOS in the Past but that did’nt work for me, I got this error many times in the Past but Randomly My PC runs Normally.
So, What do you think Is there is anything Wrong with my Motherboard or Ram Slot or Ram?? ( I have no dedicated Graphic Card btw ) Thank You So much.
Thanks for all the great information! I had to return the computer before I got this one fixed. I started with reformat and re install windows 7 and ran the other way. The only ones I didn’t get to were related to hardware. Though I did remove the battery and let it chill for a bit and looked at the hard drive, not sure why I didn’t just unplug it for a bit. Anyway if I get that sob back I will try those other things. It runs just great except for that annoying message.
Wish I could have gotten rid of it before she needed it back. I had a similar problem (after cloning my Windows 7 installation from a HDD to a new SSD) that gave me exactly the same error message.
I tried a lot, even using fixmbr and fixboot, but nothing did help. From a parallel Windows 7 installation onto the same SSD I could check that I could read all relevant files on my cloned partition, but it would not boot. Eventually I came across a tool called EasyBCD, which is able to create and modify a boot loader for choosing between several operating systems. So I created a new entry, rebooted and everything was fine: the new menu appeared and it let me choose between the two Windows 7 installations (though I needed only the one that I cloned to my new SSD). So my solution was to “just” create / modify the boot loader.
I experienced this problem for a long time, even resuming from hibernation sometimes the press Ctrl+Alt+Del to restart message would come up, sometimes would start other times I had to go into the Console and fix the MBR to get restarted. Until I noticed that this happened every time there was an external drive plugged in and the system would automatically hibernate, on resuming the message came up. To solve the problem I wrote two scripts used by “USB Safely Remove” these prevent the computer from hibernating while an external drive is plugged in, and now I have had no problem at all.
How do I use CTRL + ALT + DEL on a Mac computer? The Mac equivalent of CTRL + ALT + DEL is Command + Option + Escape. Picture of an Apple keyboard with the CMD + OPT + ESC keys circled. Hold down the CTRL and Option keys (located on either side of the space bar) then press the Escape key.
This will bring up the Force Quit window showing a list of your open applications. Choose one and press the Force Quit button to immediately end that application. Screenshot of the Force Quit window. You can also force a hanging application to quit by right-clicking (CTRL + Click) on its icon in the Dock and choosing “Force Quit” from the context menu.
What about rebooting? Macs have a separate key combination to force a reboot: Command-Option-Power. Hold down the Command and Option keys then press the power button to restart the computer. To force the computer to shut down, hold down the power button for between 5 and 10 seconds.
Forcing a reboot or a shutdown is not advised unless there is no other option. Performing these actions can result in data loss, especially if there are applications running or external storage devices connected. You should first try to correctly reboot or shut down the computer:. The right way to reboot a Mac is to click Apple → Restart Choosing “Restart” from the Apple menu. The right way to shut down a Mac is to click Apple → Shut Down Choosing “Shut Down” from the Apple menu.
