Hello, welcome. 
I'm not clear if you want: 
a) keep the Windows 8 and also install Windows 7 
b) get rid of Windows 8 and install the Seven 
 
For the second case you have to go into BIOS to disable UEFI and Legacy Mode and activate SecureBoot. 
Then boot with the dvd of Seven, remove all volúmnes disk and install the operating system. 
I do not think that is the best decision, but it is your decision. 
 
For the first case, we would talk once details what the current situation: ie Windows 8 is still alive and booting? and hit DCB content here: 
 
Symbol >> system run as administrator. 
paste the following command and give intro 
 
bcdedit / enum all> bcdedit.txt & notepad bcdedit.txt 
 
a text screen appears. 
Copy it and paste it on the forum, please.

Hello!
 
Thank you very much for answering and sorry , I go by parts:
 
1) I load the windows 8 makes some formats tales
2) I installed win7 deleting all partitions and deleted everything that was on the HD
3) disable the UEFI bios and enable legacy mode
 
In summary, windows 8 no longer have it and just have the windows 7
 
You step to copy the data displayed ( really putting partition = C: (this change I BCDedit through the internet looking for information but still gives me the same error window of HarddiskVolume1

Regarding Windows 8, I have no experience with it , but the feedback I get ( in performance) are very good .

That is why if you go to switch to W7 MBR facility Should keep the recovery discs in case you change your mind.

 

As for your installation of W7 , as I ' ve Been able to observe in the BCD we REMAIN with EFI boot manager and EFI bootloader .

I would do so , que does not mean it is right (eye , the content will be lost! )

 

Disable " Secure Boot" and check "Legacy Support" is Enable.

Disable " Fast Boot"

Save the changes

 

Booting the DVD >> select language and keyboard >> the Install Windows window below we Repair your Equipment >> Options window system recovery and give Next >> Options window in Windows Recovery Symbol system and let you type commands That there continue after each intro .

 

diskpart

sel disk 0 (a zero )

clean

convert mbr

exit

 

Closed symbol system click Reset and start the installation

 

Quick alternative :

Already have an EFI install W7 .

Just repair the BCD and It Should start:

Hello! 
 
Well I do not remember the source but I would say it was the microsoft page (could be?) 
 
It is possible that the problem comes from the ISO I am using win 7?

I go to bed, it's for my parde 
 
Starts with the dvd and the welcome screen of the installation press shift + F10, with this you will be on console. Type in 
notepad Windows \ Panther \ setupact.log 
the response is 
 
Callback_BootEnvironmentDetect: Detected boot environment: BIOS 
 
or 
 
Callback_BootEnvironmentDetect: Detected boot environment: UEFI 
 
I think yours will be the second case. Means that the image is to the bootx64.efi bootloader, the groove dvdrom booting from EFI.

I have executed the judgment desdel CMD and have located the en ... me appears instead of EFI (UEFI is the same?) 
 
 
IBS Callback_BootEnvironmentDetect: Detected boot environment: EFI 
 
 
And if I displayed this means that the fault of the ISO that I used?
