Windows 8 On Asus Laptop - Required Device Isn't Connected Or Can't Be Accessed
Aug 17, 2014
I am running Windows 8 on an Asus laptop. Two days ago it was doing updates and restarting. It did this 3 times, and on the third restart I received the blue error screen. It stated
"Recovery. Your pc needs to be repaired. A required device isn't connected or can't be accessed. Error code: 0xc0000225
You'll need to use the recovery tools on your installation media. If you don't have any installation media [like a disc or usb device] contact your system administrator or Pc manufacturer."
It gives me three options at the bottom [press enter to try again, press f8 for startup settings, press esc for uefi firmware settings]. If I press enter I get the same screen just with a bit more text. f8 does nothing. Uefi takes me to the boot menu. I have been trying to boot from a dvd r with a flash operating system in order to recover my data before it is reformatted. However, it does not seem to recognize the disc. When I select to boot from dvd rom, it tries, then on the black screen appears text saying restart and select boot device or install boot media and press a key. I tried taking disc out and putting bavk in, then pressing a key, nothing, same message.

Windows 8 has been acting up recently, every now and again my computer will blue screen and restart with the message
error-code-0xc000000f-windows-8-a-required-device-isnt-connected-or-cant-be-accessed
So far I have noticed that if you leave the computer off for a while or change the hard drive to a different sata port it will work fine for a while then do the same thing.
Also I have done a full clean install with windows 8 and the same issue has occured a couple of days later.
I have a feeling its the hard drive going bad but how can i be sure? Some hard drive utilities have reported "end to end error - fail" but others have said there is no issues.

I'm having an issue with a pc I am fixing. I reflowed the gpu and removed some viruses but now every time I restart the pc I get this message which I can fix with the installation media. But every time i fix it, once I turn the computer off again after using it normally for whatever amount of time, when I turn it on again, i get the blue screen again. What's causing it to happen every time?

I have an Asus UX31A with WIndows 8 Enterprise VL. Every time I wake the system from sleep, I hear the system chime as if a device is attached, unattached, and re-attached. I don't know what as it happens at the login screen and I'm not fast enough to see if anything appears in the taskbar.
After logging in, I get this window (see below; I had to remove a couple things I don't know if I can show). If I follow its directions, I restart and go about life until I put the system to sleep again in which the process repeats. As I write this I'm finishing a bunch of updates so perhaps that has something to do with it (I have a lot of Office and SP1 for SQL Server that I've been putting off along with a healthy swath of optional OS updates).

I have a windows 8 laptop and a linux desktop, both connected to the same screen using hdmi - since my screen has only 1 HDMI input, I use an HDMI splitter.
Every time I move from the linux to the windows 8 laptop (using a HDMI mini remote control), I get a message from windows saying that in order to apply these changes I need to reboot.
Note that I also use the same wireless keyboard and mouse for both computers - each time I change from one computer to the other, I unplug the USB that controls them and plug it in the computer I will use.
I think that the problem is related to the HDMI, not the keyboard/mouse usb - but I am not sure.
Needless to say that it is very annoying and I cant keep restarting the LT each time I move from one to the other.
I checked event viewer to see what causes this and these are the relevant messages:
1 - Device 'USBVID_045E&PID_0745&MI_017&1a5cec9a&0&0001' requires installation.
Microsoft-Windows-Kernel-PnPConfig/Configuration
Kernel-PnPConfig
Event id: 3
2 - A reboot is required to complete device installation of device 'USBVID_045E&PID_0745&MI_017&1a5cec9a&0&0001'
Microsoft-Windows-UserPnp/DeviceInstall
UserPnp
Event id: 8000
how I can fix this, make it stop requesting reboots?

I am trying to install the new develp build of Windows 8 (x86) on my asus eeepc 1005pe. This is a netbook which doesnt even have a cd/dvd drive.
So anyway, I extracted the iso on a bootable usb flash drive. I boot, and when I click install it just hangs for about 10 minutes and then it gives me this error:
I tried setting the bios from AHCI to IDE. This does not work, I even get a bluescreen of death when I boot up in the current win7 sp1 install. But anyway on google I read a lot about this problem and one of the solutions is to put it on AHCI.. but not for me as it was already on AHCI. Anyway IDE is not workin either.
Just recently I installed win7sp1 on this netbook without a problem. I checked the sha1 hashes of the Windows 8 ISO and they are confirmed, so that is not the problem either.

I have an ASUS VivoBook X200CA that is running a Windows 8.1 Upgrade. For about 5 months, this laptop has been running perfectly without any problems and I have managed to reset the computer many times due to certain errors and problems that have arisen from software and hardware compatibility.
Recently, I went to reset my laptop, it restarted and then it took me to the WinRE screen. I went into Troubleshooting > Advanced Options and I clicked on the Reset option. It then took me through each of the various warnings and making sure that my data was backed up and then, once I had clicked on the "Reset" button, it hung for a bit and then said "Reset has failed - Required Partition is Missing".

When I connect my DualShock 3 controller to my Windows 8.1 laptop it does not charge. I hear a beep, as in something was connected to the PC, then it seems to charge for a couple of seconds (lights flash on the controller) and then it stops. I am able to charge my phone and tablet so, it's just the DS3. It works fine on my Windows 7 computer, so it's not the controller.

When connecting my PC to my TV through HDMI cable sometimes the playback device does not recognise my TV. While the picture on my TV is great I don't get sound. Sometimes it works.
I am not sure if this has to do with the cable ( its a good HDMI cable though) or with the graphics card or with the TV.

Why Windows 8.1 is giving me so many issues. My laptop is unable to stay connected to the wifi for long and sometimes I am unable to connect. My phone and tablet stay connected to the wifi while my laptop can't. I tried all the remedies for it and yet it has issues. Is it because I had installed spotflux and tunnel bear on my laptop?

I've bought an HDMI cable to connect my laptop to TV, i've gone into the control panel and checked that "show disabled devices" and "show disconnected devices" are both allowed and still i dont seem to get an option for HDMI for audio. The picture has come through fine, but nothing I do with the audio seems to work.

I upgraded my Windows 7 to Windows 8 pro back in November. Windows explorer has always had issues but now I cant open windows explorer (any way) without it crashing and reload. In SAFE MODE it seems to work fine. I have tried disabling all the Services (non MS) and the Startup function but in normal mode but Windows Explorer still crashes.
I'm definitely not the only one experiencing this issue. A quick search online shows other people reporting their Windows 8 explorer frequently crashes. Is there a solution or something I should try to see if it can resolve the issue?

I have an Acer M5-581T laptop with windows 8.1 (windows 8 was already installed when this laptop was bought) and has been running fine since i received it. Last night I accidentally dropped the the right hand side of my computer about 2 or 3 inches but no more. I didn't think anything of it until this morning when i tried to start up my computer and was successful until when i tried to open an application on my desktop and my computer froze. Also when i started up my computer i heard a scratching or cracking sound in the right hand side and this continued for the nect couple times i tried to restart my computer.
So, after it froze I restarted my computer just by holding the power button and upon turning it on again after the Acer start up screen i got the message "No bootable device. Hit any key." in a blue box. Hitting any key did nothing obviously. After some research i was able to press F2 and open up BIOS but with messing around with the settings and even changing in secure mode from UEFI and Legacy BIOS doesn't seem to work. Pressing control+alt+delete doesnt work, it only restarts my laptop. I haven't really done anything like try to change my laptop from windows 8 to windows 7 so it is still windows 8.1.

Asus laptop Windows 8 stuck at Resetting PC 2%, Only option is hard reset??
This laptop belongs to my Grandma (87 years old). **She did not make the recovery disk for the computer.**
I got to the Recovery options and it has been stuck at 2% for about 6 hours. Asus OEM X55C Windows 8
NOTE: Yesterday I told Grandma I would see what was wrong, but it would bug out, freeze, etc when trying to log into the administrator. The screen would go totally black and then freeze. So, the computer has shut down improperly several times.
However, it did repair the disk last night before I attempted this recovery.

I have an Asus laptop with Windows 8. I got it last August and until last week I haven't had any problems with it. Last week, my sound stopped working. It shows that the sound is up all the way on speakers and system sounds, but I am only able to get sound when I plug my headphones into the headphone jack.

I am trying to set up a backup for a Windows 8 ASUS laptop. The backup is to go to a local network shared external drive. The folder for the back up was named Sue_ASUS_bkup and it was mapped as "W". The backup tools > Win 7 file recovery only provides a DVD as a backup location. It does not show a hard drive nor the network location as options.

I just recently bought asus notebook x550C i3 processor,had been working fine for a week. Then lost connection to Internet went to update and restart as updates were needing to be done. After appearing to complete the updates, it then said failure configuring updates, reverting changes do not turn off. It has now been on this screen for 3 hours. I have tried shutting down but when re opens it lands back on same page, with the loop going round and round. I have tried f9, as another forum said that should get me to menu to restore factory settings but that does not work, neither does windows key

I have an ASUS laptop (N53Jq, i7, GT425M, 8GB) with Windows 8.1, with update. It's being used like a desktop computer, with the lid closed connected to a monitor through HDMI and with mouse and keyboard. I have the Power4Gear Hybrid driver, to set the high performance mode in my PC, but after awhile it still goes into sleep mode (like 1 or 2 minutes). It's really weird, I checked every setting (on the driver app and control panel) and sleep mode is off everywhere.

This is a brand new windows 8 system that was sold to a customer. He brought it in for being unable to boot into windows after having used it for a couple of weeks, and he demonstrated the issue to me. It literally just boots to grub. This customer is a basic windows user. No experience with linux or dual booting. He uses it for email. I have never come across this particular problem before, so I ran the normal partition tools to see if the table looked proper for a windows 8 machine. Everything checks out ok, however it is still booting to a grub prompt!!

Windows 8 Asus laptop dead hard drive
I understand all I need to do is install and it will pickup serial from bios and be activated
I found a windows 8 pro dvd but it did not activate maybe because laptop came with basic. I want to activate it without an activator as its not my laptop, and it did come with windows 8 genuine on it. I notice all the links here are dead and all the torrent are for other than basic windows 8.

I have an Asus laptop running on Windows 8 that starts up to the initial Asus logo for a minute and then restarts over and over. I've already tried pressing f8 and it does nothing so I cannot get anywhere to attempt to fix the problem.
Unfortunately I do not have the Windows disk so I'm looking for a solution outside of having to buy another one and wiping the hard drive to reinstall.

I've bought a new laptop , it's an Asus K95 series. (K95VB)
Since it has an open slot for a second drive i also bought an SSD for it , a Crucial M500 240Gb if that should matter.
So the laptop comes preinstalled with windows 8. There are no discs (recovery,repair,...) with the system. (a google search learned that this is normal)
Offcourse i want my laptop to run the Windows 8 from the SSD instead of the 1TB HDD (wich is actually a 3.5" , first time i see that in a laptop ).
1) What is the best way to do this ? Clone , fresh install , recover to SSD ? (alltough it seems the last one isn't possible)
I know a clean install is always the best way but since i don't have any Windows 8 disk to install from , i don't know how ... (read as : can you do a fresh install with a recovery disk ?)
2) How do i do it ? (a nice step by step if possible)
3) If i manage to do it , what do i do with the original HDD ?
Because it has 5 partitions now : 100MB (EFI-systempartition) - 900MB (recoverypartition) - 20,01GB (recoverypartition) - and a C and D (OS and Data).
Can/may they be deleted ? (want to use this just for data , all progams/games/apps will go to the SSD offcourse)
Haven't installed anything yet , just turned it on and did the basic installation stuff Windows 8 asks for the first time.
Not a noob to pc/laptop installs , but new to Windows 8 and it looks like it changed a bit since W7 and everything before that.

I've just received an Asus S301L laptop, with Windows 8 Pro preinstalled. The owner wants Windows 8 wiped and Win7 installed along with Scientific Linux.
I've disabled secure boot and enabled CSM in the BIOS, thus getting rid of the annoying UEFI boot process, and I'm now able to boot old-style from thumbdrives and whatnot.
My question is: given this partition configuration as shown by gparted, is it safe to wipe the whole damn thing and repartition from scratch, or will I run into bootup problems with the BIOS not seeing stuff where it wants to see it (like that suspicious FAT32 partition labeled "boot")?
I imagine this isn't a problem since I disabled everything UEFI, but better safe.

I have a Asus Laptop operating with Windows 8.1. It connects to wifi but none of the desktop icons can get to the Internet. Meanwhile most window tiles in the start menu have Internet access . For example I have the application "MegaTube" and that application has access to the Internet. As well as the weather app, which updates when connected to the Internet.

Ever since the feature 'about:tabs' has existed in IE, I have been using it as my home page. 90% of the time, if I open IE, I will want to launch one of the ten most often accessed pages.
Since installing Windows 8.1 and IE11 which came with it, 'about:tabs' is not working consistently, most of the boxes remain empty, and those that previously were filled become empty. What changed?
