Start from scratch again.
Delete with FDISK all partitions. Restart all the time when asked.
Then FDISK /MBR
Create partition(s) with FDISK. Make one as active.
Check you harddrive by running scandisk from just bare DOS before Win95 install (though isn't able to find all the errors as Win95 can).
After that you install Win95.
Any problem, look through README *.txt files on the Win95 CD, try to use appropriate IGNORE option(s).
If the Scandisk continues to give you an error massage, you HDD or the CD are probably bad.
Good idea to copy the Win95 CD on the HDD and do install from the harddrive.
