Win7 set up interrupted, now won't load software

I have a new machine and was starting the setup.
The specs are:
Acer Aspire M5910
Win7 Home Premium 64-bit
3GB RAM
HDD 1TB

When I put it on, the set up started but didn't recognize the keyboard or mouse. Since I was stuck, I switched off the computer and started again. This time all seemed well, the set up started and the 'location' window was OK. But, then the mouse wouldn't work and I couldn't get out of the set up. So, I switched it off again. After hooking up a different keyboard and mouse, I tried again.

Now, I am in a continual loop of Win Error Recovery and Windows Boot Manager

Windows Boot Manager tells me to Insert Win installation disc and restart computer.
Software is preloaded, so I don't have this and since I couldn't set up, I don't have a recovery disc.

Below, it says:
File:\Windows\ststem32\config\system
Status: 0xc000014c
Info: Windows failed to load because the system registry file is missing, or corrupt.

Help with solving this problem would be hugely appreciated! Many thanks

Thank you for the help. A great relief!
Have downloaded the iso file.
I am currently on my old machine, WIN xp.
Do I create the cd in the usual way ... will that be OK for the new Win7 machine?
Sorry ... having had one problem, I don't want to create another for lack of asking a basic question!

Thanks.

Re: creating disc as per your advice ...

Error window came up .....
"Confirm Stream Loss"
The file 'windows-7-64-bit-repair-disc.iso' has extra information attached that might be lost if you continue copying. The contents of the file will not be affected.

It looks as if the iso file copied onto the dvd .... is it OK to assume this or is there a way to double check all is well, before I start the repair?

Many thanks.

I have a new machine and was starting the setup.

I would return to seller for FREE REPAIR or Replacement. Use the warranty.

Many thanks to both gregrocker and theog for your time and advice.
I have tried to create the dvd with the iso file, but no success. I downloaded ImgBurn & it looks very useful. Unfortunately, it seems that my plextor has died; it's not something that I use very often.

My last thought is whether I can get the iso file onto a usb flash drive? I have ones that have enough capacity.

If this can't/doesn't work, then I'm off back to the shop where I bought it.
Many thanks again. What a weekend!

Since you're trying to burn a DVD I'm assuming you've got the Win7 installation ISO which requires a DVD, instead of Win7 Repair CD ISO. Win7 Home Premium x64 SP1 English Official ISO download

Write the ISO to flash stick using Universal USB Installer with Win7 in dropdown menu.

Then boot using Acer one-time BIOS Boot Menu key F12, while HD remains set to boot first in BIOS setup.

Follow these steps to get a clean reinstall of factory OEM: Reinstalling Windows 7

If you intend to try repairs first, use the DVD's System Recovery Options to run Startup Repair repeatedly.

I am being very stupid .... should have been cd. Apologies.
Too much reading so as to try and do the right thing ... and I end up doing the wrong thing. Time to stop and take a break before taking any action. I will report back. Thank you once again.

Now that it is Monday, I talked to Acer's tech help. They explained and talked me through using the key combinations that return the machine to default factory settings. That worked and all is now OK, the computer installation is complete.

Many thanks again for the help over the weekend. Even though I wimped out at following the ISO-flash drive remedy, I have learned so much in the past couple of days and will continue to learn through reading here at the forum. The support is terrific and much appreciated.
