Windows 7 Recovery Disk Shows Operating System: Unknown On (Unknown)?
Oct 18, 2012
When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.
Ghost Shot> This was about a week ago my Windows 7 started acting up right before the big patch Tuesday. I've been running it for over a year now and it's been solid. When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing restores from Ghost 15,etc. Anyway, ghost was backing up my system C: drive before last week. I have yet to even try and use Ghost to see if it would successfully restore my OS but I've been using it to backup my C: drive anyways. Prior to last week it could backup my C: drive fine. I might try a Ghost restore point from a few weeks back before this happened but not sure yet[CODE]

Installed new hard drive and Windows 7, wireless card shows up as unknown device.I was having major stability issues with windows. I wanted a new hard drive so i installed it and a new copy of windows. The wireless worked fine before, and ethernet works fine now. It shows up in device manager as other devices, network controller with a yellow exclamation mark. I have gone to Dell to install the driver. It almost finishes then says you do not have a recognized wireless device.
My comp is a Dell Inspiron M5010, I installed windows 7 HP 64 bit same as what was on before. WHDPC, K5Y6D are the numbers I have found for the card. I have tried several different drivers and all have the same error.
how to get windows to recognize the card so the drivers I install will recognize it? There are many threads about this in various places, but none of the solutions work.

There is a unknown 'portable' device (F:/) on my computer which I dont recognize. I saw it when I was about to scan my computer with Norton and was about to select which drive I wanted to scan, if I show hidden files it also shows up under My Computer, but I cant access it.... What could cause this?

I've been working on renaming all my music for the past few weeks using a program called Tag&Rename. I have over 350 Gbs of music so it's been quite the undertaking but I've made a fair bit of progress. Until all of a sudden in the middle of renaming some albums today I was shocked to find that all my albums from A through S were just...not there anymore. All my work had just vanished for no apparent reason. I had just deleted a redundant music folder when this happened and thought that maybe I had somehow deleted more than I asked for but there's no trace of the folders anywhere not even in the recycle bin. I did a complete search of my computer looking for Bob Dylan just to see if I had somehow put all the files in some other folder by mistake but no luck. So I downloaded a bunch of free undelete software packages and scanned my hard drive and they couldn't even find the missing files. It's as if they just vanished. Is there any software out there that can help me in my search, or does anyone know what could have happened? I don't mind paying up to a hundred bucks if I can just get my lost work back. I obviously need a program that will maintain my original folder structure since renaming files and folders and changing my folder structure is all I've been doing. I have most of the music backed up on another drive but it's all mistagged and disorganized. I really don't want to start all over again.

This unknown "Local Disk Q" just showed up this morning, and my regular external drive was gone. I reconnected my external to another port, and that went fine, but this locall disk q remains, and can not be accessed, changed, removed, etc. I scanned for virus's, and all seems ok. How can I remove this, and where did it come from?

This just popped up today and the only thing I can think that I had done since not seeing it was activated AHCI. As can be seen in the attached snip there is a very small partition to the left of the "SSD Common" logical partition. It is bounded by the same green box as the "SSD Common" partition. Hovering over it provides details of it being Free Space 1Mb in size. Right clicking on it provides a menu with everything greyed out except for HELP which simply opens the Disk Management user guide. Should add that both the "SSD General" & "SSD Trade" are Windows 7 bootable partitions with AHCI activated.

Recently I noticed that two unknown icons now show up in my system tray, having icon graphics of "A" "9". Double clicking on them, right-clicking, or simply hovering my mouse over them unfortunately does nothing -- I don't know what they are. I'm concerned they could be something malicious. Please see the attached screenshot that shows these 2 icons. I've also attached another screenshot showing all processes in the Task Manager.

What I had initially: Quote: 120 GB hardisk divided into 3 partitions.1st partition (22.2GB) with XP, second partition (30GB) with win 7 and rest (60 GB) as mass memory for storage.What I did: Quote: Installed Ubuntu 12.04 LTS desktop 32 bit with USB on the partition which had XPFor that I had to format it and convert to ext4 and also create a swap memory of ~3GB.Thus I finally have 1 partition with ubuntu another with win 7 and another with mass memory.Now, Problem:MBR got damaged as win XP partition was formatted (which had bootloader) and thus I can't login to win 7 from Ubuntu Grub.To solve this problem I had to create a USB recovery disk for Windows 7. But now the problem is even after using bootrec command which gave sucess result for fixmbr, fixboot, scanos and rebuildbcd i am not able to boot into win 7. The computer just hangs after bootup with a blinking cursor.

So when ever I get an update notice to update Internet explorer 9 and I try updating it, it always cancel because of some weird error that windows cant troubleshoot. I try downloading it from the Microsoft website, and it doesn't install. It says it does but I still end up with ie7. I know tootle chrome is 100x better but I have it and I think upgrading it will boost my system performance a bit.

I have a new Dell Inspiron laptop with Windows 7 Business and went to connect to my wireless home network on a Linksys router and Win 7 detects other networks in the area, but my network SSID is not listed. I reset the router thinking that maybe the issue, but I havd another laptop and desktop and both are working fine with the network and router on the web.I then realized that Win 7 had in the available wireless listings a "unknown" network, when I select that network to connnect it ask for an SSID, It type in my SSID and it then connects to the internet.
BUt when I turnoff or reboot the laptop it will not automatically reconnect at start up. I have selected in the preferred wireless networks to connect automatically, but because it keeps seeing an unknown wireless network, I have to manually reconnect and re-type in my SSID.Does anyone know why Win7 keeps seeing my Linksys as an unknown network and how to make it reconnect automatically at startup.

I am not really worried about this, just curious. My OS is win7 and I just finished copying a few hundred music videos from some DVD's to my PC. I decided to look at the properties of one of the videos and this is what I find under the security tab in the Group or user names box.
Account Unknown(S-1-5-80-random numbers...
I looked this up and found several bits and pieces of info but nothing to clearly describe what this is or why. These videos were downloaded and burned to DVD's on this same PC but an older OS, Win XP and a different user name. I am guessing this account unknown is because of the permissions granted by windows media player for the streamed info pertaining to artists and the names of their songs but I don't know for sure.

I have had Win 7 installed for a while now).
Here is a summary of my problem:
1) My computer recently got stuck on the "Starting Windows Screen." So I manually held the power button to reboot.
2) On reboot, it said there was a need to run a startup repair, which I did. Everything checked fine, except for the last one which said "System Volume on Disk is Corrupted," which it claimed to have successfully fixed.
3) After rebooting from repair, the system gets stuck on "Starting Windows Screen" for a good 10-15 minutes, after which it runs a registry check. After it completes that I get hopeful -- but the screen then gets stuck on an all black screen with just the mouse cursor and nothing more.
4) Additional note: Attempting to start the computer on "safe mode" leads safe mode startup to become stalled on "DRIVERSCLASSPNP.SYS"
5) The lastest attempt to repair yielded this message: "Startup repair cannot repair this computer automatically.
