Windows 7: Toshiba SatelliteL455-S5976 Blk screen on boot with mouse cursor help

My gf's running win 7 not sure on what edition, but lately she installed a program which I also use called advanced system care 6 off cnet.com. It has been working fine, she has been complaining to me of a lag when playing bejeweled on facebook. All of a sudden today she turned it on and its a black screen with the mouse cursor, it asked if you wanted to do a system repair, i clicked no at first and later tried doing it, nothing happens back to black screen. Control alt del doesn't do anything, can't get into safe mode, safe mode with command prompt doesn't work, nothing works and we don't have a boot cd, tried pulling battery holding down pwr and restarting to get back to black screen with mouse. So i'm at a loss on what to do. I am pretty computer savvy myself. Just can't get into windows. It does the windows loading green bar then to the black screen with mouse cursor. Any thoughts on where i can get or download a win 7 copy even? or atleast something that can get me into win?
thanks
Craig

Beware of Advanced System Care. It has cause many people problems.

Well she turned it on and it went from having a movible mouse on the black screen to read disk err with a blinking cursor and says hit Ctrl alt del to reboot and goes back to same screen. I see u posted a link. I'm on a iPod so really hard to read and zoom. Kinda looking for some direct ideas on how to fix it since net access is very limited. Thanks

ok, so if i'm using kaspersky rescue disk and when i go to download the iso file, there is a file above it thats labeled ... the file size is 1024, so whats that? important?

After downloading do you not see an ISO file which you can rightclick to Burn or Open with Windows Image Burner?

I'd use Windows Defender Offline if you can't get into Safe Mode with Networking to run Malwarebytes.

While it's important to check for infection first since Windows 7 may not repair if infected, the crapware likely corrupted the install requiring Startup Repair to be run several times with reboots.

This should offer to run System Restore but if not run it manually to go back if possible before the tweaky junkware was imposed on Windows 7.

Everything else possible to do to start Windows 7 is also there leading up to if necessary rescuiing your files to run Toshiba HDD Recovery Utility or the superior Clean Reinstall - Factory OEM Windows 7 .

I just ran the kaspersky rescue disk, nothing found, it only give me a warning before program loads saying failed to unmount hard disk and which means failed to make swap. It also says ETH-0 failed predicting i have a htcp or something. I run wireless net so thinking thats the eth error. What is the unmount prob though?

Can you get into Safe Mode with Networking to run Malwarebytes full scan?

If not run Windows Defender Offline. You only need a scan or two to confirm no infection before moving on to the Repair steps.

No, I thought I said way up at the first post, not able to get into safe mode at all. I am at a black screen of death. nothing works and I don't have a rescue or windows 7 disk to reinstall from. kinda up a creek.
